Find the point-slope equation for the line that passes through the
points (7, -21) and (-4, 23). Use
the first point in your equation.
y- [?] = [ ](x-[])

Step-by-step explanation:

1) First, find the slope of the line between the two points. Use the slope formula, . Substitute the x and y values of (7, -21) and (-4, 23) into the formula and simplify:

So, the slope of the line is -4.

2) Now we have all the information we need. To write the equation of the line, use the point-slope formula and substitute values for , , and .

Since represents the slope, substitute -4 in its place. Since and represent the x and y values of a point the line intersects, substitute the x and y values of (7, -21) into the equation as well. This gives the following
