Solving Linear Equations Using...


Slope and y-intercept
X and Y Intercept
Practice:
1. Rearrange each equation into the form y=mx+b. State the slope (m) and y-intercept
(b).
a. 3y = 6x + 9
b. 3x + 6y – 12 = 0
c. 5x = y - 9
d. 2x + 2y = 2
2. Graph each equation using a table of values (Use xЄ {-2, -1, 0, 1, 2})
a. y = 3x – 1

3. Determine the x and y intercepts for each equation
a. x + y = 10
b. 2x + 4y = 16
c. 5x - 7y = 35
d. 50 - 10x - y=0
4. Graph each equation by using the intercepts (hint, first find the intercepts)
a. x + y = 4
