Oops I was wrong the first time it's actually -6, first choice

Step-by-step explanation:

Just plug in -3, so x will now be -3

f(-3)=-3^2-(-3) = -(3)^2-(-3) = -9+3 = -6

It's -6 as the equation did not parentheses -3 together so you can only multiply 3

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
