Question

Find the slope of the line.
A. 1/2

B. -1/2

C. -2

D. 2
(graph in answers)

Answer 1

here's a formula you can use to find the slope:\[\frac{ y _{2}-y _{1} }{ x _{2}-x _{1} }\]
where x and y are the (x,y) values of two points on the line.

Answer 2

can you identify two points on that line?

Answer 3

-3 and -3???

Answer 4

not exactly.. a point should be represented in a (x, y) form. the x representing its location on the x axis (horizontal) and the y representing its location on the y axis (vertical)

Answer 5

for example, one of the points would be (-4, -1). can you name another one?

Answer 6

(-3, -1.5) ?

Answer 7

right! now when you plug in your x and y values of those two points, it should look something like this\[\frac{ -1.5-(-1) }{ -3-(-4) }\]can you solve it from there? or at least simplify?

Answer 8

2.5, 1

Answer 9

simplified, it would look something like this:\[\frac{ -0.5 }{ 1 }\]
You need to divide -0.5 by 1, that will be your slope.
