Question

for the given line, what are the slope and y - intercept? slope: ex. 1 y - intercept

Explanation:

Step1: Identify two points on the line

From the graph, we can take two points. Let's take (0, 50) and (200, 10).

Step2: Calculate the slope

The slope formula is $m=\frac{y_2 - y_1}{x_2 - x_1}$. Substituting the values: $m=\frac{10 - 50}{200-0}=\frac{- 40}{200}=-\frac{1}{5}=-0.2$.

Step3: Determine the y - intercept

The y - intercept is the y - value when x = 0. From the point (0, 50), the y - intercept is 50.

Answer:

Slope: - 0.2, y - intercept: 50
