(m+3)(m+3)
m^2 + 3m + 3m + 9
m^2 + 6m + 9
Answer:
its A
Step-by-step explanation:
i literally just took the test
Find the gradient:
m = y2-y1 / x2-x1
m = 6-(-4) / 0-1
m = 10 / -1
m = -10
Slope intercept form:
y = mx + c
Input the values from one of the points to find c (imputing (1,-4) to y=mx+c):
-4 = -10(1) + c
-4 = -10 + c
c = -4 + 10
c = 6
Therefore, the equation is:
y = -10x + 6
The answer is 7:17 because when you add them together it equals 7:17.
