Question:

what is meant by the slope of a line that passes through the following points: (0,1) and (5,8) what is the slope formula?


Answer:

The “slope” of a straight line passing through two points is the “angle of the line”.

slope formula = “rise” over “run”, or “rise” DIVIDED BY “run”

slope formula = (change in “y” values)/(change in “x” values)

slope formula = (y₂ - y₁)/(x₂ - x₁)


The x-y coordinates of your two points are: (0, 1) and (5, 8).

Points

Left and Right

(0, 1) and (5, 8)

(x₁, y₁) and (x₂,y₂)

x₁ = 0
x₂ = 5

y₁ = 1
y₂ = 8

slope formula = (y₂ - y₁)/(x₂ - x₁)

slope formula = (8 - 1)/( 5 - 0)

slope = (7)/( 5)

Slope = 7/5



>>> The slope of the line passing though your two points is: Slope = 7/5




Thanks for writing.
