write the equation of the line that passes through each pair of points in slope-intercept form. (3,4),(4,6)
First, get the slope = m = [6 - 4] / [ 4 - 3] = [2] / [1] = 2
Using this and one of the points - I'll choose (3,4) - we can write
y - y1 = m(x - x1)
y - 4 = 2 (x - 3)
y = 2x - 6 + 4
y = 2x - 2 and that's in slope-intercept form
