Answer:
y=4x-8.5
Step-by-step explanation:
Use point- slope form, since you are given one point and one slope.
y-y₁=m(x-x₁)
Plug coordinates and slope in.
y-(-1/2)=4(x-2)
Solve
y+1/2=4x-8
y=4x-8.5
Combine the two equations in the right amounts to eliminate y :
-2 (2x + 3y) + (3x + 6y) = -2 (17) + 30
-4x - 6y + 3x + 6y = -34 + 30
-x = -4
x = 4
Solve for y :
2x + 3y = 17
8 + 3y = 17
3y = 9
y = 3
Answer:
134.73
Step-by-step explanation:
Solving for m:
243 = m + 108.27
243 - 108.27 = m + 108.27 - 108.27
134.73 = m
y = 1x + 3, also y = 1x + 4 both of those are parallel
Answer:
umm the answer is 18x+2y²
