Slope = (10 - 5)/(-9 + 15) = 5/6
y = mx + b where m = slope and b = y-intercept
b = y - mx
b = 5 - (5/6) (-15)
b = 5 +12.5
b = 17.5
Equation y = 5/6 x + 17.5
Y-intercept = 17.5
X-intercept when y = 0
So
5/6 x + 17.5 = 0
5/6 x = -17.5
x = (-17.5) (6/5)
x = -21
Answer
Y intercept (0, 17.5 )
X intercept (-21 , 0)
A is (2,-4) B (-2,5) C (0,-6) D(-4,-3) E(3,0) F(5,4)
Given,
The expression is:
By using the middle term splitting method,
Hence, the factor is (x-(7+sqrt(33)/4)) (x+(7+sqrt(33)/4)).
