Recall that the **slope-intercept form** of a linear equation is:

**y = mx + b** , where '**m**' is the **
slope** of the line and '**b**' is the **y-intercept**.

**y = 3x + 6** ==> **m** = **3** ,
**b** = **6**

Thus, the slope of the line is **
3** and the y-intercept is **
6**.

The y-intercept is when the line crosses the y-axis, so when x = 0

y = 3(0) + 6 = 6, so the y-intercept is 6

the slope is 3, as you know y = mx + b, m is the slope
