Question

The line has a slope of 7 and passes through the point (5,3)

Answer 1

The equation of the line is in the form

`y=mx+b`

in which m represents the slope of the line and b is the y-intercept.

according to the information given m=7

to find the y-intercept we can use the point given.

`y=7x+b`

using point (5,3)

`\begin{gathered} 3=7(5)+b \\ 3=35+b \\ 3-35=b \\ -32=b \end{gathered}`

the equation of the line is

`y=7x-32`
