Question

Write in slope-intercept form an equation of a line that passes through the points (-1,2) and (1,-6)

Answer 1

Answer: y = 6 - 4x

Step-by-step explanation: Find the slope: (y2-y1) / (x2-x1). In this case, [2-(-6)] / (-1-1) = 8/-2 = -4. Then write it in intercept form, substituting in a point for y and x: 2 = a -4(-1). Then balance to get a = 6. So y = 6 - 4x
