The slope is
and y-intercept is -10
Step-by-step explanation:
Given equation is:

The given equation is in slope-intercept form
General form of slope-intercept form of equation of line is:

Here
m is the slope
b is the y-intercept
So,
comparing both equation we get
The coefficients of x

And

Hence,
The slope is
and y-intercept is -10

Y=ax² + bx + c and A(-2,18), B(0.4), C(4,24) given
1)Let's determine 1st the value of c in using the pair of B
4= a(0)² + b(0) + c , c=4 and y=ax²+bx+4
2) Use the pair of A: 18 = 4a -2b + 4===> 4a-2b=14
3) Use C pair: 24 = 16a+4b+4 ==> 16a+4b=20
4) solve the system equation in 2) and 3) and you'll find a=2 and b=-3
Hence the equation is y =2x²-3x+4
6(y+8) is the answer but you didn’t finish the equation so
