Answer:
m = - 1/4
Step-by-step explanation:
When two line is perpendicular to each other the product of them is - 1
So let the other line be B
Gradient of B = t
Gradient of A = 4
therefore m = - 1/4
Start by distributing the to the
.
Multiply and simplify.
Rearrange the terms.
Combine like terms.
Add on both sides.
Divide both sides of the equation by .
