Answer:
(0,-24)
Step-by-step explanation:
f(x) = (x – 8)(x + 3)
To find the y intercept, set x=0
f(0) = (0 – 8)(0 + 3)
f(0) = (-8)(3)
f(0) = -24
The y intercept is
(0,-24)
First find slope.
slope=change in y/change in x (y2-y1/x2-x1)
slope=4-3/-2-(-4)=1/2
Now we need to find the x intercept.
y=mx+b
3=1/2(-4)+b
b=5
So the equation is y=1/2x+5.
The slope m=(y2-y1)/(x2-x1)
m=(8-4)/(5-1)
m=4/4=1
now let s solve the constant b
y=x+b
8=5+b
8-5=b
3=b
now we know the slope m=1 and the constant b=3
let s write the equation is
y=x+3 <--------- Final answer
