Complete the point-slope equation of the line through

Grace [21]

<h2>Answer:</h2>

First: info on point-slope form.

Formula: <em>y - y₁ = m(x - x₁)</em>

We need to find the slope of the line first.

$m = \frac{2 + 1}{5 - 1} = \frac{3}{4}$

Slope: $\frac{3}{4}$

Now we can complete the point-slope equation of the line.

$y - (-1) = \frac{3}{4}(x - 1)\\\\y + 1 = \frac{3}{4}(x - 1)$

*These equations are equivalent.
