Question

Which of these expressions shows a correct way to set up the slope formula for the line that passes through the points (3, 6)

and (-7, -4)?

Answer 1

C

Explanation:

Line slope calculation formula: The difference of the second components is divided by the difference of the first components. It should be noted that they are reduced in order. The components of a point on the numerator and denominator must always be written first.

Answer 2

C

Explanation:

Slope formula:

`\mathsf{slope=((y_2-y_1))/((x_2-x_1))}`

where
`\mathsf{(x_1,y_1)}` and
`\mathsf{(x_2,y_2)}` are points on the line

Given:

• 
  `\mathsf{(x_1,y_1)=(3,6)}`
• 
  `\mathsf{(x_2,y_2)=(-7,-4)}`

`\mathsf{slope=((-4-6))/((-7-3))}`
