Question

What is the slope of a line perpendicular to x - 5y = -10?

Answer 1

? anybody care to help I got m=2 correct or missing a step?

Answer 2

gradient 1 X gradient 2 = -1 for perpendicular lines.
gradient of the slope you have can be found if you get the equation into y intercept form. So y to one side and x to other...
x+10 = 5y
so 5y/5 = x/5 + 10/5
or y = (1/5)x + 2
so m1 * m2 = -1
if m1 = 0.2,
0.2*m2 = -1
m2 = -1/.2
= -5.

Test -5 * .2 = -1
A perpendicular line has slope of -5.

Test y = -5x and y = 0.2x
