whats an equation in slope-intercept form for the line that crosses through the points. (-1, 7) (-7, -11)?

Answer 1

slope = m = (7--11)/(-1--7) = 18/6 = 3

y=mx + b where m=slope and b = y intercept

y=3x + b, plug in either point to solve for b

7 = -3 + b

b =10

y=3x +10 is the equation of the line through the two points (-7,-11) and (-1,7)
