Question

Write a slope equation for slope=-8/7; (-3,1)

Answer 1

The Solution.

Step 1:

We shall state the formula for a slope-intercept equation.

`y=m(x-x_1)`
`\begin{gathered} \text{Where m = slope = }(8)/(7) \\ x_1=-3\text{ (the value of x in the given point coordinate)} \end{gathered}`

Step 2:

We shall substitute for the values of the parameters in the formula above.

`\begin{gathered} y=(8)/(7)(x--3) \\ \\ y=(8)/(7)(x+3) \\ \text{Cross multiplying, we get} \\ 7y=8(x+3) \\ 7y=8x+24 \end{gathered}`

Step 3:

Presentation of the Answer.

The correct answer is 7y = 8x + 24
