Chapter 12: Q54. (page 637)

Write an equation in slope-intercept form for each graph.

Short Answer

Expert verified

The equation of the graph in slope-intercept form isy=-2x-2.

Step by step solution

01

Step 1. Given Information.

From the given graph, the line passes through -1,0 and 0,-2. The equation of the line in slope-intercept form is to be determined.

02

Step 2. Calculation.

The equation of a line in slope-intercept form is y=mx+b, where m is the slope of the line and b is the y-intercept.

Here b=-2.

The slope of a line passing through two points is given by:

m=y2鈭�y1x2鈭�x1m=鈭�2鈭�00鈭�鈭�1m=鈭�20+1m=鈭�2

03

Step 3. Conclusion.

Hence, the equation of the graph in slope-intercept form is y=-2x-2.
