Write a linear function f with f(−9)=10 and f(−1)=−2

First we need to find the slope of the function

The slope of a function is equal to

So now we plug this into the equation and find the slope (M will represent the slope)

So the slope is -3/2

Now we can use point-slope form.

Point slope form is represented by

So when we plug in our values we get

So the equation is

Y = -3/2X-7/2

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .
