find the slope of the line that passes through each pair of points. SHOW ALL YOUR WORK including the slope formula
(3,5) and (1,6)

Answer 1

Slope M are 3/4, 1/7

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.
