Question

Is the line through the points R (-1, 3) and S (2, -7) parallel to the graph of the line given by the equation, 10x + 3y = 6?

Answer 1

A. No, the slopes have opposite signs.
B. Yes, the slopes have the same sign and value
C. Yes, the lines both decrease to the right
D. No, The lines have unequal slopes.

I think it's A or D. Definetly not B

Answer 2

In the equation isolate "y" first can u do that?

Answer 3

Divide 3y and 6 by 3?

Answer 5

Parallel lines will always have equal slopes.

Answer 6

10x + 3y = 6?

First you'd solve for y in this equation, and that'll give you y = mx + b, where m is the slope.

Then, use the slope formula and plug in R (-1, 3) and S (2, -7), and see if the slopes are equal.
