Assuming the equal sign is supposed to be +
-88 - (18)^2
-88 - 324
-412
Answer:
y=2x
Step-by-step explanation:
compute the slope first-
(-2,1) and (2,9)
m = 9-1/2-(-2) = 8/2+2= 8/4 = 2
knowing the slope take a given point and substitute it's x and y values into the equation to solve for 'b' the y-intercept-
y = mx + b,
1 = 2(-2) + b,
1 = -4+ b,
b = 5
our equation is y = 2x + 5
if you want an equation parallel to the line it has to have the same slope. Take y = 2x
5w + 3.8 = 16.3
5w + 3.8 - 3.8 = 16.3 - 3.8
5w = 12.5
5w ÷ 5 = 12.5 ÷ 5
w = 2.5
Hope this helps!!
