writing an equation given two points on the line
write the equation of the line that passes through the points (7,-4) and (-1,3), first in point-slope form, and then in
slope-intercept form.
the slope of the line is
when the point (7.-4) is used, the point-slope form of the line is
the slope-intercept form of the line is

Step-by-step explanation:

The slope-intercept form of an equation of a line:

m - slope

b - y-intercept

The point-slope form of an equation of a line:

m - slope

The formula of a slope:

We have two points (7, -4) amd (-1, 3).

Calculate the slope:

The point-slope form of an equation of a line:

Convert to the slope-intercept form:

       use the distributive property

    subtract 4 = 32/8 from both sides
