It is already in simplest form
Hope this helps you!
When it is perpendicular, the slope is the negative reciprocal so it would equal -3/2x. Plug in the points to the equation so you can find the intercept. -8=-3/2(4)+b
Combine: -8=-6+b
Add 6: -2=b
The equation would be f(x)=-3/2x-2
Hope this helped and sorry if I am wrong!
Answer:
The official answer is {C} ive previously taken the test
Step-by-step explanation:
I have taken the test before hand.
Slope = (-2 - 10)/(12 + 6) = -12/18 = -2/3
y = mx + b
10 = -2/3(-6) + b
10 = 4 + b
b =6
equation
y = -2/3x + 6
<span>x-intercept when y = 0
</span>-2/3x + 6 = 0
-2/3x = -6
x = 6 (3/2)
x = 9
answer is <span>d.9</span>
