Find the value of r so that the line passes through (-5,4) and (3,r) so that the slope is equal to -1/2.

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.
