Answer 1

Use the slope formula

Answer 2

i got -7/5 but its not rite i dont think

Answer 3

Here's the formula:
\[\frac{y2-y1}{x2-x1}\]
When you plug in the points you get:
\[\frac{7-0}{2-(-3)}\]

Answer 4

am i rite

Answer 5

No, but you were close, it was actually 7/5

Answer 6

you can also notice, that when x gets bigger (move to the right), the line goes up (its y gets bigger). that means the slope is *positive*

if you did not know the formula, you could start at the first dot, and count up to the height of the 2nd dot (that is change in y). then count over to get the change in x. you would get change in y=7 and change in x = 5 so the slope will be 7/5

or use the formula

(-3, 0) and (2, 7)
take the 1st y:0 minus the 2nd y: 7 0-7 = -7
take the first x: -3 minus the second x: 2 -3 -2 = -5

slope = -7/-5 which simplifies to 7/5 (minus divided by minus is plus)
