Question

Find the slope of the line passing through (-4, 4) and (-4, 8)

Answer 1

Undefined

`\sf \bold{ slope \ formula : \ (y_2-y_1)/(x_2-x_1) }`

insert the following coordinates

`\hookrightarrow \sf (8-4)/(-4-(-4))`

`\hookrightarrow \sf (4)/(-4+4)`

`\hookrightarrow \sf (4)/(0)`

Hence, following the rule [ (a/0) is undefined ] The slope is undefined.

Answer 2

`\Longrightarrow: \text{The slope is 0.}`

Explanation:

The slope formula is used to determine the slope of the line.

Slope formula:

`\Longrightarrow:\sf{(Y_2-Y_1)/(X_2-X_1) }`

y2=8

y1=4

x2=(-4)

x1=(-4)

Rewrite the problem down.

`\sf{(8-4)/(-4-(-4))=(4)/(0)=\boxed{\sf{0} }`

• Therefore, the slope is 0, which is our answer.
