# 9.5.4. Equation of the Straight Line Given Its Slope and Its y–Intercept

Find, in the form of

- A
- B
- C
- D

### Example

Find, in the form of

### Solution

We know that equations for straight line graphs can be written in the form

First, rearrange

Comparing this equation to

Then find the slope,

We know also that if 2 straight lines,

So, we know that

Therefore,

The slope of the required line is

Then find the

We are told in the question that the line crosses the

Therefore,

Substituting for
