Question

Graphs

Information given: Y=4/5x+(-3)
Slope: m= 4/5
Y-intercept= -3

What I need to know :
Write the equation of the line that will intersect at a 90 degree

Answer 1

`\displaystyle y=-(5)/(4)x-3`

Explanation:

Recall that perpendicular lines form a 90-degree angle, so the slope of the line perpendicular to the given equation will be the opposite reciprocal.

Hence, the equation of the line that will intersect at a 90-degree angle is
`\displaystyle y=-(5)/(4)x-3`
