Question

Which is the slope of the following equation?

y = -x - 2

A. 1
B. -1
C. 2
D -2

Answer 1

In slope-intercept form, whatever is before the x is the slope and whatever is after, including the sign is the y-intercept.

Answer 2

k

Answer 3

If what is before the x is a whole number, you have to remember whole numbers are just numbers over one. So if it is 5x, the slope is 5/1

Answer 4

ok

Answer 5

y = mx + b.....m is the slope and b is the y intercept.
so you have y = -x + 2.....if there is no number in front of the x, just a sign, then it is the sign you have and 1...so the slope is -1 and the y intercept is 2.
Understand ?
