Question

The equation of line WX is y = −2x − 5. Write an equation of a line perpendicular to line WX in slope-intercept form that contains point (−1, −2).

Answer 1

Y=mx+b M=slope

Answer 2

for a perpendicular line the slope would be the negative reciprocal of the slope in the given equation so the slope of the perpendicular like would be m=1/2
so you would have y=1/2x+b

Answer 3

Then you would have to plug in the points given into the x and y so solve for b
so you would have -2=(1/2)(-1)+b

Answer 4

the equation should be y=1/2x+the answer for b :)
