There is a line that includes the point (7, –1) and has a slope of –17 . What is its equation in slope-intercept form?

Answer 1

put in point intercept form first: y-y1 = m(x-x1) where m is slope and (x1,y1) is a point on the line:

y --1 = -17(x-7)

multiply right side out and change y--1 to y+1:

y + 1 = -17x + 119

solve for y:

y = -17x + 118
