Answer:
(4, 1)(7, 12) = 3.67 or 3 ²/₃
(0, 0) (4, 2) = 0.5
(0, 5) (3, 0) = -1.67 or -⁵/₃
(2, 5)(2, -3) = undefined
(3, -2)(-2, 3) = -1
Explanation:
To find the slope when given two points, you can use slope intercept form which looks like this:
Slope = y₂ - y₁ ÷ x₂ - x₁
To find the slope of (4, 1) and (7, 12) we just need to insert them into the slope intercept form equation.
(4, 1) (7, 12)
x₂ y₂ x₁ y₁
Slope = (1 - 12) ÷ (4 - 7)
Slope = ( -11 ) ÷ ( -3 )
Slope = 3.67 or 3 ²/₃
(2, 5)(2, -3) = undefined
When graphed, these two points would make a vertical line. If you try to apply the slope intercept form, you will get a denominator of 0 making the slope undefined.
