Question

Write the equation of the line in the graph. Use the points (-4,6) and (8,3) to find the

slope.

Answer 1

9514 1404 393

Answer:

y = -1/4x +5

Explanation:

The slope is given by the formula ...

m = (y2 -y1)/(x2 -x1)

m = (3 -6)/(8 -(-4)) = -3/12 = -1/4

The graph crosses the y-axis at y=5, so the slope-intercept equation can be written as ...

y = mx +b . . . . . line with slope m and y-intercept b

y = -1/4x +5 . . . . line with slope -1/4 and y-intercept 5
