Question

PLEASE HELP ME.

Answer 1

Answer is  y = -x+4  (choice D)

======================================

Work Shown:

Find the slope of the line through

(x1,y1) = (0,4) and (x2,y2) = (3,1)

Use the slope formula

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

m = (1 - 4)/(3 - 0)

m = (-3)/(3)

m = -1

The y intercept is 4, so b = 4. This is where the graph crosses the vertical y axis. The y intercept is always where x = 0.

With m = -1 and b = 4, we go from y = mx+b to y = -1x+4 which is y = -x+4

Answer 2

The answer is D. Y=-x+4
