Question

1. **What is the slope of a line that passes through the points (-1,30) and (4, 10)

Answer 1

Slope = -4

Explanation:

Given points are :

(-1,30) and (4, 10)

We need to find the slope of the line that passes through these points.

We know that, the formula for the slope of line is given by :

`m=(y_2-y_1)/(x_2-x_1)`

We have, x₁ = -1, y₁ = 30, x₂ = 4 and y₂ = 10

Put values in the above formula.

`m=(10-30)/(4-(-1))\\\\=(-20)/(5)\\\\=-4`

So, the slope of the line is -4.
