Answer:
m = - 2.27 or m = 16.27
Step-by-step explanation:
Given
m² - 14m - 37 = 0 ( add 37 to both sides )
m² - 14m = 37
To complete the square
add ( half the coefficient of the m- term )² to both sides
m² + 2(- 7)m + 49 = 37 + 49, that is
(m - 7)² = 86 ( take the square root of both sides )
m - 7 = ± 
( add 7 to both sides )
m = 7 ± , that is
m = 7 - ≈ - 2.27 or m = 7 + ≈ 16.27
Solution is x=2 and y=-3
check the slopes since both are in slope int form
y=mx+b
m=slope
b=yint
we see one line has a slope of -2 and yint of 1
another one has a slope of 1/2 and yint of -4
y=-2x+1 and y=1/2x-4
1/2x-4=-2x+1
last one
Answer:
D
