Slope is -2/5 and the y-intercept is 100

Mrrafil [7]

Answer:

$y=-\frac{2}{5}+100$

Step-by-step explanation:

With the given information, we can write the line equation in slope intercept form. $y=mx+b$

The slope, m, is -2/5

The Y-intercept, or b, is 100.

Replace m with -2/5 and b with 100.

$y=mx+b\\y=-\frac{2}{5}x+100$
