Question

Write the equation of a line with a slope of 3 and passing through the point (-5, -7).

Show steps please

Answer 1

y = 3x +8

Explanation:

`(-5 ,-7)=(x_1,y_1) \\m = 3\\`

Plug in values into point-slope form

`y -y_1 =m(x-x_1)\\y - (-7) = 3(x - (-5))\\y +7 =3(x+5)\\y+7 =3x+15\\y = 3x +15-7\\y = 3x +8`
