i need help finding the slope of the line that passes through each pair of poinst.
Divide (y2 - y1) by (x2 - x1). For (1), this would be 6/3 = ?
Thank you. The first one came out to 2.
The second one is not working out. I got 4 1/2 and I know that's not correct. I did (-2x2)-(5x1) divide by
Don't multiply. (x2-x1) just means taking the second x value and subtracting the first x value from it. So as far as the x values go for the second problem, you'll have (-2 -5). As far as the y's go, you take the second y and subtract the first y. (1-0).
Can you get it from there?
I think I got it.
I redid both.
(1,-3) (4,3); 3-(-3)=6 divided by 4-1=3
(5,0) (-2,1); 1-0=1 and -2-5=-7 so -1/7 is the slope. I hope that's correct?
(1-0)/(-2-5) = -1/7, so that's correct.
