## anonymous one year ago Find the value of x or y for which the line through A and B has the given slope m. A(-2,3), B(4,y), m=-2/3

1. anonymous

Label the coordinates of A $$(x_1, y_1)$$ and the coordinates of B $$(x_2, y_2)$$. In this case we have $$x_1 =-2$$, $$y_1 = 3$$, $$x_2 = 4$$, and you are trying to solve for $$y_2$$. Slope is calculated using$m=\frac{ y_2-y_1 }{ x_2-x_1 }$Substitute in the known values and solve for $$y_2$$

what exactly do i plug in?

The values of m, x1, y1, and x2. Everything is given except for y2 which you are to find.
