Answer:
Slope M are 3/4, 1/7
Step-by-step explanation:
Step-by-step explanation:
1.) Slope M = change in y ÷ change in x
That is,
M = (y1 - y2)/(x2 -x1)
Given the following points:
A (10, 4) and B (–2, –5) C (–7, 1) and D (7, 8) E and F(-2, 2/3)
The slopeM between point A and B will be
M = (-5-4)/(-2-10)
M = -9/-12 = 3/4
The slope M between point C and D will be
M = (8-1)/(7+7)
M = 7/14 = 1/7
The slope M between point E and F will be
2.) The slope of a line passing through (1, 7) and (3, 9) will be
M = (9-7)/(3-1)
M = 2/2 = 1
But Robert say The ratio = (1-3)/(7-9) = 1
Though Robert will eventually get the Same value but that is not the correct method of calculating slope.
3.) Point A (1, 3) B (4, 2) C (–2, 4) do not lie on the same lines. If they do, they will all have the Same value for x or the same value for y.
