Domain is all the x values represented
domain here is infinitely because it can go on forever to the left and to the right
The answer is -3
-12c = 43 - 7
-12c = 36
÷ -12 ÷-12
c = -3
Answer:
y+4=-3(x+0) or y=-3x-4
Step-by-step explanation:
so you have to make it in form y=mx+b
that would be y=1/3x-2/3
for a perpendicular line, you would need to find the opposite reciprocal of the slope
3/1 or 3 would be the reciprocal, so to make it opposite would be -3
So it would be y-y1 = m(x-x2)
fill it in with the coordinates (0,-4)
y+4=-3(x-0)
to get it to slope intercept form you have to simplify, and after that you get y=-3x-4
-8
f(x) is y, in which x is the independent variable
when x = 5, y = -8
