 Question 374699: please help me solve this What equation of the line passes through the points with coordinates (-2,1) and (1,2)Answer by sophxmai(60)   (Show Source): You can put this solution on YOUR website!Ok, so your coordinates are (-2,1) and (1,2). The equation of the line is y=mx+b First, find the slope, m. Now, you have Now, plug in one of the coordinates in for x and y, and then solve for b (the y-intercept). And now you have To check to see if this is correct, sub in x or y of one coordinate and see if you get the other value (sub in x, get the correct y, or sub in y and get the correct x). (-2,1)
