Point-Slope Equation The _{
}.is used to determine the equation of a line given a point on
the line and a slope.Find the equation of a line through (4,1) whose slope is _{
}.
Find the equation of
a line through (5,-7) perpendicular to In order to use the point-slope form, it is necessary to have a point and the slope. Find the slope from the given line. Solve the equation of the line for y to determine the slope.
To find
an equation of a line
After finding the equation of the line in
slope-intercept form you may be asked to change the equation back into the
standard form of Ax + By = C.
Now the equation is in the standard form.
