Question

COORDINATES GRAPH a. y=-2x-1 and b. y=1/2x-1

make two observations you can make with this

Answer 1

now it's fine.

Answer 2

the slope for the first one is -2.

and for the second one is 1/2

Answer 3

its going to be perpendicular

Answer 4

whereas the y-intercpts are same.

Answer 5

yes, these lines are perpendicular since the slope of b is -1/(slope a)

Answer 6

can u show me how to graph them please

Answer 7

Sure

Answer 8

thanks

Answer 9

For the first equation, you'll have to make a point on your y-intercept of -1. Since your slope is -2, you will have to go two units down from the y-intercept of -1, and then go one unit to the right, because it is -2/1.

For the second equation, you will have to make a point at y-intercept of +1, and go one up and 2 to the right as your slope is 1/2.
