Write an equation of a line in point-slope form that has a slope of -2 and passes through (5, -1).

Answer:

$y+1=-2(x-5)$

Step-by-step explanation:

We can write the equation of a line in 3 different forms including slope intercept, point-slope, and standard depending on the information we have. We have a point given and a slope from the equation. We will chose point-slope since we have a point and the slope.

We will substitute $m=-2$ and $x_1=5\\y_1=-1$ .
