**how do I convert 6x- y=-5 so that I can graph it?**

1. Two different variables are present: X and Y

2. Remember that you want the following format: **y = mx + b**

** 6x- y=-5 **

** - y=-5 - 6x Subtract 6x to bring it to right side of equation**

** y=5 + 6x Divide -1 at both sides of equation to bring -1 to right side**

** y=6x +5 --------> y = mx + b**

**2 OPTIONS FOR GRAPHING**

**OPTION 1:** Choose any number for x, plug it into y = mx + b eqn and get y value. You get a point.

Example) If guess x=2 ----> y = 6(2) + 5 ----> y = 17 ----> point (2,17)

If guess x=0 ----> y = 6(0) + 5 ----> y = 5 -----> point (0,5)

Since mx + b = y is the equation form of a ** line**, you need

**atleast to graph!**

*2 points***OPTION 2:** Use mx+b=y equation form to find slope and intercept and graph

Example) mx+b=y equation is y = 6x +5

Y-intercept (b): Number adding to x value is **5. Point in y-axis crossed by line of equation**

** (0,5)**

Slope (m): Coefficient of x (number multiplying x) is **6 = 6/1**. **Change in y over change in x**

**Move vertically up 6 and right 1 from (0,5)**

**Line: You come to another point away from (0,5) and you draw line through these two points. **

better to chopoints or more points. however, the question is how to change the equation
