Answer:
equation y=-11/50-2
Step-by-step explanation:
Y intercept is where you start which is -2. Then you calculate the slope m=x1-y1/x2-y2
I believe it would be 6. the first number and exponent are usually your quadratic terms
BC = 18
AB = AC, hence
8x - 4 = 5x + 11 ( subtract 5x from both sides )
3x - 4 = 11 ( add 4 to both sides )
3x = 15 ( divide both sides by 3 )
x = 5
BC = 4x - 2 = (4 × 5 ) - 2 = 20 - 2 = 18
