## why.math 3 years ago Choose the point-slope form of the equation below that represents the line that passes through the points (−3, 2) and (2, 1). y + 3 = −5(x − 2) y − 2 = −5(x + 3) y + 3 = −(x − 2) y − 2 = −(x + 3)

The equation is of the form y - y1 = m(x - x1) (x1, y1) is either of the given points; "m" is the slope. Find the slope. m = (y2-y1)/(x2-x1) ....= (1-2)/(2+3) = -1/5 However, this slope is not in any of the options, and I checked my work, so either you mistyped something, maybe one of the points, or the people making the book made a mistake. Plug in either point for y1 and x1 in the equation. Apparently they used (-3, 2). y - 2 = -(1/5)(x - (-3)) y - 2 = -(1/5)(x + 3)

x+5y=7

5y=7-x y=(7/5)x-(1/5)

Yes, I agree with computergeek. I think you have a typo

idkthats what ive been trying to tell my teachers.. they say the answers there.. but thanks for trying

Have your teacher work it out, just make sure you copied it correctly

ok thanks again
