Step-by-step explanation:
Hello!
A line that is perpendicular to another has an opposite-reciprocal slope.
Meaning:
- Flip the sign (+/-)
- Flip the fraction
The slope perpendicular to 3/5 would be -5/3.
We can solve for the y-intercept by plugging in the x and y values given from the coordinate into the equation with out new slope.
<h3 /><h3>Solve for B</h3>The y-intercept of the new line is 20.
The equation is
Minus ka from both sides
u=ba-ka
undistribute a
u=(a)(b-k)
diivde both sides by (b-k)
u=ba-ka
undistribute a
u=(a)(b-k)
diivde both sides by (b-k)
