Question

Passes through (5,5), slope = 4

Answer 1

The slope intercept form is given by:

`y=mx+b`

Where

m is the slope

b is the y-intercept (y-axis cutting point)

Since slope = 4, we can write:

y = 4x + b

To find b, we put (5,5) into x and y in the equation, respectively. So, we have:

`\begin{gathered} y=4x+b \\ 5=4(5)+b \\ 5=20+b \\ b=5-20 \\ b=-15 \end{gathered}`

Final Equation:

`y=4x-15`
