Answer:
C -1/2
Step-by-step explanation:
SLOPE IS THE GRADIENT OF THE LINE
THAT'S CHANGE IN Y OVER CHANGE IN X
-4-1/4--6
-5/10
=-1/2
Answer:
y=2
Step-by-step explanation:
since the line is horizontal, on the point 2 on the y axis, the equation is 2. If, however the line were to be diagonal, it would have been different, as would it if the line were vertical(in which case, the equated would start x =)
Hope this helps
I'd suggest re-wording your question:
"How do I find the ordered pair (x,y) that solves this system of linear equations?"
One way of doing that would be to substitute y=5x+7 into the other equation:
-3x - 2(5x+7) = -12. Solve this for x. Once you have a value for x, subst. that value into y=5x+7 to find the corresponding y value.
Then write the ordered pair (x,y). That's it.
Divide 6 by -1. Remember that -y is really -1y.
Answer:
8Parallel lines always have the same slope.
