Question

Algebra help please?

Answer 1

The graph below shows a line segment AB:

graph of line AB going through ordered pairs negative 1, 5 and 2, negative 4

Which of the following equations best represents the line segment AB?

y = -3x + 2

y = -2x + 1

y = -3x - 2

y = -2x - 1

Answer 2

@jigglypuff314 @mathmale

Answer 3

y = mx + b
where m=slope and b=y-intercept

so first, what is the slope between points (-1,5) and (2,-4) ?

Answer 4

-3?

Answer 5

yes :)
then you have y = -3x + b

then temporarily plug in a point like (-1,5) for (x,y)
so 5 = -3(-1) + b solve for b

Answer 6

2?

Answer 7

So B?

Answer 8

yes 2
so y = mx + b
where m=-3 and b=2

Answer 9

Awesome! Do you mind helping me with a few more? (:
