Question

Write an equation for each condition

1) The line with a slope of 7 and a y-intercept of -1( in slope-intercept form)

2) The line that passes through (1,-5) and has a slope of 3 (in point-slope form)

Answer 1

1.

`m=7\\ b=-1\\\\ y=7x-1`

2.

`y-y_1=m(x-x_1)\\ y_1=-5\\ x_1=1\\ m=3\\\\ y-(-5)=3(x-1)\\ y+5=3(x-1)`
