Question

what is the y-intercept of y=-2x-7 and how do u get it

Answer 1

The y-intercept is -7 and it is gotten from the value of "b" in the slope-intercept form of a line:

y = mx + b

Your equation is already in that form, so you just match up the b with the "-7".

Answer 2

put x=0. it will be your answer...

Answer 3

-2x-7=-9x

Answer 4

Incidentally, that form also gives you your slope as "m" or -2

Answer 5

i have to graph it though

Answer 6

so y=-9/x... i think
