Write an equation of the line parallel to y=3x−7 that passes through point (2, 4).

1 answer:

6 0

Parallel lines share the same slope. y=3x+7 has a slope of 3, so that is the slope of the parallel line. Then use y=mx+b an plug in (2,4).
y=3x+b
4=3(2)+b
4=6+b
b=-2

So the equation is y=3x-2

Solve the system of equations by elimination. <br><br> 2x + 2y = -2<br><br> 3x - 2y = 12

valkas [14]

Answer:

Step-by-step explanation:

2x + 2y = -2

3x - 2y = 12

5x = 10

x = 2

2(2) + 2y = -2

4 + 2y = -2

2y = -6

y = -3

(2, -3)
