Write the equation in slope intercept form of the line that has a slope of -3 and contains the point (1,1)

Answer 1

You want to get your line in the form

y = mx + b

The line has slope m = -3 and contains the point (1,1).

All you need to do now is use the point given to solve for b

1 = -3(1) + b

1 = -3 + b

Add 3 to both sides to solve for b

4 = b

So your line is

y = -3x + 4
