Answer:

-11/4

Explanation:

y = mx + c

Point (x,y)

intercept c

slope m

-9 = m(4) + 2

-9 = 4m + 2

make m the subject of the formula

4m = -9-2

4m = -11

divide both sides by 4

m = -11/4

Answer:

-11/4

Explanation:

The y intercept has the coordinates of (0,2)

We have two points (0,2) and (4,-9) so we can find the slope using

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

= ( -9-2)/(4-0)

= -11/4
