Answer:
Line C is the correct answer
Step-by-step explanation:
A: y = (-20/3) * x + 56
B: y = (-10/3) * x + (80/3)
C: y = 2 * x + 8
D: y = (27/7) * x - 7
check: line C -- y = 2 * (-7) + 8 = -6 (-7, -6)
y2 = 2 * 6 + 8 = 20 (6, 20)
y3 = 2 * 2 + 8 = 12 (2, 12) .... correct
Answer:
To convert a quadratic from y = ax2 + bx + c form to vertex form, y = a(x - h)2+ k, you have to Get ready to create a perfect square trinomial. BUT be careful!! In previous completing the square problems with a leading coefficient not 1, ... Take half of the coefficient of the x-term inside the parentheses, square it, and place it in the box.
hope this helps :)

Answer:
y=(-3/5)x
Step-by-step explanation:
5x-3y=20
-3y=-5x+20
y=(5/3)x-(20/3)
perpendicular lines have opposite reciprocal slopes
Answer:
15x+5
Step-by-step explanation:
First you distribute the 5 to the 3x ( 5 times 3x=15x)
Next you distribute the 5 to the 1 (5 times 1=5)
Finally you put the two answers together 15x+1
you cant simplify it anymore because you cannot add 15x to 1
