Question

Find the slope of the line that passes through the pair of points. (1,4),(-5,4)

Answer 1

`(-1)/(2)`

Explanation:

To find slope with two points we use the following formula
`(y^2-y^1)/(x^2-x^1)`. So y 2 is 4 and y 1 is 1 so 4-1 is 3 and now x 2 is -5 and x 1 is 1 so -5 - 1 is -6 so the slope is
`(-3)/(6)` and simplifying it we get
`(-1)/(2)`.

Answer 2

0

Explanation:

slope = (y2 - y1)/(x2-x1)

slope = (4-4)/(1-(-5))

slope = 0

line is at horizontal state and perpendicular with y-axis is point 4
