Step 1. Put the given equation in y-intercept form, y=mx+b, and identify the slope (m) and the y-intercept (b)
Step 2. Put a dot on the y-axis at b.
Step 3.
Apply the slope. (Connect the dots)

Directions: Sketch the graph of a line below.
2y-6x=-8
Step 1. Put the equation in y-intercept form (y=mx+b).
| Add 6x to both sides. | 2y=6x-8 | |
| Multiply both sides by 1/2. | y=3x-4 | |
| Identify m (slope) & b (y-intercept). | m=3 & b=-4 |
Step 2. Put a dot on the yaxis at b.
Step 3. Apply the slope.
Directions: Graph the lines.
Directions: Please write 1-2 paragraphs that thoroughly address the following.
1. The equation 2x+3y=10 is not in y=mx+b form. Is it the equation of a line?
2. Consider the following equation:
To put it in y=mx+b form, should you divide both sides of the equation by 1/2 or multiply both sides of the equation by 2? Does it matter which one you do? Why or why not?
