Answer:

y = -5/4x +1

Explanation:

The slope-intercept form of a line is given by

y = mx + b where m is the slope and b is the y intercept

We are given the slope and a point on the line

y = -5/4 x + b

We can substitute the point for x and y and solve for b

-9 = -5/4(8)+b

-9 = -10+b

Add 10 to each side

-9+10=-10+10+b

1 = b

The slope intercept form of the equation is

y = -5/4x +1
