Question

Find the slope of the line passing through the points (9, 1) and (-3, -3). Describe the slope as positive, negative, zero, or undefined. The slope equals The slope is (select)​

Answer 1

Given points:-

• (9,1)
• (-3,-3)

We have to find slope =m

• As we know that

`{\boxed{\sf Slope_((m))=\frac {y _2-y_1}{x_2-x_1}}}`

• Substitute the values

`\qquad {:}\longrightarrow\sf m=\frac {(-3-1)}{(-3-9)}`

`\qquad {:}\longrightarrow\sf m=\frac {-4}{-12}`

`\qquad {:}\longrightarrow\sf m={\frac {1}{3}}`
