Standard form for slopes

Question

passes through (9,-56) which has a y-intercept of -2

Answer 1

y= mx + b is the standard equation in slope and y intercept form. plug in the point and intercept to get

-56 = m(9) -2 where m= slope

9m = -56 +2 = -54

m = -54/9 = -6 = the slope

y=mx +b = -6x -2

y = -6x -2

or

6x + y = -2
