Question

and the temperature, in degrees fahrenheit. during that time, the temperature rose, stayed steady, and fell, at different rates. on the set of axes below, suav created a graph of temperature over time.

graph with temperature (°f) on y - axis (50 - 75) and time (6 am, 12 noon, 6 pm, 12 midnight) on x - axis, showing temperature changes: starts at ~56°f at 6 am, rises to ~64°f, then to ~72°f at 12 noon, stays steady until 6 pm, then falls to ~68°f, then to ~64°f at 12 midnight

how hot was it when the temperature held steady?

Explanation:

Step1: Identify the steady temperature segment

The temperature held steady (horizontal line) between noon and 6 pm.

Step2: Read the temperature value

From the graph, the y - value (temperature) during this steady segment is 72°F (by looking at the vertical axis, the points on the horizontal line are at 72°F). Wait, looking at the graph, the vertical axis has 70, 75, etc. Wait, the points on the horizontal line: let's check the grid. Each grid line: from 55 to 60 is 5, so each small grid is 1? Wait, the first point at 6 am is 56? Wait no, the first point is at 6 am, temperature 56? Wait no, the y - axis: 55, 60, 65, 70, 75. The horizontal line is between noon and 6 pm. The y - coordinate of those points: let's see, the vertical distance from 70: the point is 2 units above 70? Wait no, maybe each grid square is 1. Wait, the horizontal line is at 72? Wait no, maybe I misread. Wait, the graph: at noon, the temperature jumps to a point, then stays steady until 6 pm. Let's check the y - axis labels: 55, 60, 65, 70, 75. The horizontal line is at 72? Wait, no, maybe the points on the horizontal line are at 72? Wait, no, looking at the graph, the vertical axis: the horizontal line is between 70 and 75, and each small grid is 1. So the temperature when steady is 72°F? Wait, no, maybe I made a mistake. Wait, the first point at 6 am: (6 am, 56), then (let's say 10 am? No, the x - axis: 6 am, noon, 6 pm, midnight. The first segment: 6 am to before noon: from 56 to 64 (wait, the second point is at 64? Then noon to 6 pm: horizontal line at 72? Then 6 pm to midnight: decreasing. Wait, no, the problem's graph: the vertical axis is temperature (°F), with 55, 60, 65, 70, 75. The horizontal line (steady) is at 72? Wait, no, maybe the correct value is 72? Wait, no, looking at the graph, the two points on the horizontal line (noon and 6 pm) have a y - value of 72? Wait, maybe the grid is such that each major grid is 5, and minor is 1. So from 70, the point is 2 above, so 72. But maybe I was wrong. Wait, the problem: when the temperature held steady, what was the temperature? Looking at the graph, the horizontal line is at 72°F? Wait, no, maybe the correct answer is 72°F? Wait, no, let's re - examine. The vertical axis: 55, 60, 65, 70, 75. The horizontal line is between noon and 6 pm. The y - coordinate of those points: let's count the grid lines. From 70, moving up 2 units (each unit is 1), so 72. So the temperature when steady is 72°F? Wait, no, maybe the answer is 72°F. Wait, but maybe I misread. Wait, the graph: the first point at 6 am is (6 am, 56), then (let's say 10 am, 64), then noon (12 pm) to 6 pm: horizontal line at 72, then 6 pm to midnight: decreasing to 64, then to 64? No, the last point is at midnight, 64? Wait, no, the third point (midnight) is at 64? Wait, no, the problem's graph: the vertical axis is temperature, with 55, 60, 65, 70, 75. The horizontal line (steady) is at 72°F. So the temperature when it held steady is 72 degrees Fahrenheit. Wait, but maybe the correct value is 72. Alternatively, maybe the horizontal line is at 72. So the answer is 72°F.

Wait, maybe I made a mistake. Let's look again. The vertical axis: 55, 60, 65, 70, 75. The horizontal line is between noon and 6 pm. The y - coordinate of the points on that line: let's see, the distance from 70: the point is 2 units above 70, so 72. So the temperature when steady is 72°F.

Answer:

72 degrees Fahrenheit (or 72°F)
