## anonymous one year ago What is the slope of the line passing through the points (2, 5) and (0, −4)?

so its 2/1? @triciaal

3. triciaal

given 2 points the slope of the line is the change in y relative to the change in x

do move from A to B how many spaces do you have to go up or down ? this is your change in y to use the numbers 5 + 4 = to move from A to B how many spaces left or right? this is the change in x the slope is the ratio of change in y/ change in x sometimes referred to as the rise / run notice keep the same direction A to B

12. triciaal

you will get the same answer if you use B to A the important thing is to use the same direction when finding the difference

13. triciaal

when you subtract a negative the result is positive 5 - (-4) = 5 + 4

14. triciaal

are you ok now?

(x1, y1) and (x2, y2) (2, 5) and (0, −4) (-4) - (5) -------- = ( 0 ) - (2) - 4 - 5 -------- = ? @alyssawessels 0 - 2
