Question

What is the equation in point-slope form of the line given Point: (–3, 7); Slope: 4?

Answer 1

Given a point `(x_1,y_1)` and a slope `m`
the point-slope form of a line is
`(y-y_1)/(x-x_1) = m`
or
`y-y_1 = m(x-x_1)`

Using the second version with the point `(-3,7)` and slope `4`
`y-7 = 4(x+3)`
