i need help finding the slope of the line that passes through each pair of poinst.
1. (1,3),(4,3)
2.(5,0), (2,1)
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
(1x2)(0x1)= 9/2
Don't multiply. (x2x1) 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. (10).
Can you get it from there?
Amy :)
I think I got it.
I redid both.
(1,3) (4,3); 3(3)=6 divided by 41=3
(5,0) (2,1); 10=1 and 25=7 so 1/7 is the slope. I hope that's correct?
(10)/(25) = 1/7, so that's correct.
YEA!
