Question

A system of equations has no solution. If y = 8x + 7 is one of the equations, which could be the other equation?

y = 8x + 7
y = 8x – 7
y = –8x + 7
y = –8x – 7

Answer 1

y=8x-7 is the answer. hope this helps!

Answer 2

Option B. y = 8x - 7

Explanation:

Parallel lines don't have the common points or the points of intersection.

In a system of equations has no solutions out of which one equation is y = 8x + 7

So a line parallel to this line will have no solutions.

For parallel lines slope will be same as 8, so the equation will be

y = 8x - 7

Option B. y = 8x - 7 will be the answer.
