At what point will 3y=4x-6 and 8x-6y=-30 intercept
tester [92]

Answer:

The lines don't intercept

Step-by-step explanation:

we have

3y=4x-6

isolate the variable y

Divide by 3 both sides

y=\frac{4}{3}x-\frac{6}{3}

simplify

y=\frac{4}{3}x-2 -----> equation A

8x-6y=-30

Isolate the variable y

6y=8x+30

Divide by 6 both sides

y=\frac{8}{6}x-\frac{30}{6}

simplify

y=\frac{4}{3}x-5 -----> equation B

Compare equation A and equation B

The slopes are the same and the y-intercepts are different

Remember that

If two lines has the same slope, then the lines are parallel

therefore

In this problem line A and line B are parallel lines

The system of equations has no solution, because the lines don't intercept
