7. Find the slope between (3, 1) and (5, 7) without graphing the points. 8. How can you generalize your strategy for #7? How can we find the slope between any points (a, b) and (c, d)? Explain.

I really only need question 8.

Can you answer my question? will mark brainiest!

How can you tell when x and y are not directly proportional?

Type the correct answer in the box. consider the system of linear equations below. rewrite one of the two equations above in the form ax + by = c, where a, b, and c are constants, so that the sum of the new equation and the unchanged equation from the original system results in an equation in one variable.
