The points in the table lie on a line. find the slope of the line (x- 0, 1, 2, 3) (y- (-1), 0, 1, 2)
10 points and picking

Basically, how to find the slope, I suggest using the slop equation which is:

y2-y1 (divided by)

x2-x1, so if i plug in any two points on the line... I will use (0,-1) and (1,0) to find the slope, plug in the points and the equation will be:

0-(-1)  = 1

1-0 = 1

divide:

1/1 = 1

so the slope is 1 but the right way to show the slope is in the formula

y=mx+b, m is the slope and b is the y intercept with our slope (1) the equation is

y=1x+b and b would be -1 because in the points given 0 is with negative 1 so the final formula would be

y = 1x - 1

saving = more money

step-by-step explanation:

if you have 100 bucks, and you want to buy a candy bar, even if you have one at home, if you choose not to buy it, you save.

x = 3 ± √(5+y)
