Question

Line KL has an equation of a line y = 4x + 5. Which of the following could be an equation for a line that is perpendicular to line AB?

y = 4x − 8
y = 1 over 4x − 8
y = −4x − 8
y = −1 over 4x − 8

Answer 1

Standard equation of a line is.
y=mx+c

Answer 2

y = −1 over 4x − 8

Answer 3

Ur given equation of a line is
y=4x+5

Answer 4

If u compare these 2 equation of line, then u will get m=?

Answer 5

Anyway mis the slope of ur given line

Answer 6

C
m=4
Right?
