Point slope form: y1-y2=m(x1-x2)
Given the slope -4 and the set of coordinates (4,-9),
y+9=-4(x-4)
I plugged in the slope and coordinates. Since -9 came after a subtraction sign, I corrected the subtraction to addition, leaving the above point slope form equation.
I hope this helps :)
Answer:
Step-by-step explanation:
we will multiply first
-4x+16=12
-4x=12-16
-4x=-4
x=1
Answer:
13
Step-by-step explanation:
f(-2) means you want to find the y value when x=-2. Plug in x=-2 into the f(x) equation to get: [-3(-2)]-2 = 6-2 = 4.
so f(-2)=4
But the question asks for f(-2)+9. So you add 9 to f(-2) which is 9+4 = 13
