Answer:
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 and a slope from the equation. We will chose point-slope since we have a point and can find the slope.
Point slope:
We must find the slope using the slope formula.
Slope:
We substitute and
in our new equation because it is perpendicular to it. This means we will need to change it into its negative reciprocal which is
.
We will substitute and
.
This is the equation of the line perpendicular to the equation line through the points given that crosses through (14,8).
