Question

Which of the equation of the line with slope 3 that contains point (-1,5)

Answer 1

The point-slope form:

`y-y_1=m(x-x_1)`

We have the slope m = 3 and the point (-1, 5). Substitute:

`y-5=3(x-(-1))`

`\boxed{y-5=3(x+1)}` use distributive property

`y-5=3x+3` add 5 to both sides

`\boxed{y=3x+8}` - slope-intercept form
