A line on a coordinate plane passes through the point (4,6) and has a slope of -1.5

When the line passes through x=-2 what is the value of y?

Hello Amar. Ok, this is the information you have, • slope (m) which is -1.5 • point (4, 6) Now, you want to know the value of y when x= -2, then you need to use the linear equation in the point-slope form because you have slope, a point, and the value of x for the second point. Slope= m=rise/run= (y2 -y1) / (x2 – x1) then you have, - 1.5= (y2 -6) / (-2-4) Solving, -1.5 (-2-4) = y2 -6 -1.5(-6) = y2 -6 9 = y2 -6 y2 =9+6 y2 =15
