Question

the y - intercept of the graph of y=-7x + 140 is located at (0,c). what is the value of c? show calculator

Explanation:

Step1: Recall y - intercept formula

The y - intercept of a linear equation \(y = mx + b\) is the value of \(y\) when \(x = 0\).

Step2: Substitute \(x = 0\) into the equation

Given \(y=-7x + 140\), when \(x = 0\), we have \(y=-7\times0+140\).

Step3: Calculate the value of \(y\)

\(y=0 + 140=140\). Since the y - intercept is at the point \((0,c)\), then \(c = 140\).

Answer:

140
