Question 273235
Write the equation in slope-intercept form of the line that has a slope of -3 and contains the point (4, -5)

Equation of line is y=mx+b where m is the slope and b is the y-intercept (or vertical intercept or (0,b)).

y = -3x + b (plug in (4,-5) and solve for b)
-5 = -3(4) + b
-5 = -12 + b
-5 + 12 = b
7 = b

y = -3x + 7
