What is 1/2?
Is this written in slope intercept form or standard form?
y = -x + 2
Slope intercept
Write an equation in slope-intercept form when slope = 3 and the y-intercept is 2
What is y = 3x + 2?
Write in standard form: y = -8x - 3
What is 8x + y = -3?

21
DOUBLE JEOPARDY: Is this written in slope intercept form or standard form?
y=-2x+2
Slope-Intercept Form
Write in slope-intercept form: slope = 1/4; y-intercept = -6
What is y = 1/4 x - 6?
Write in slope-intercept form: 5x + 3y = 15
What is y = -5/3 x + 5?
Which number is the slope?
y = 4x + 20
4
3x + y = - 2
Solve for y first.
What is -3?
Is this written in slope intercept form or standard form?
y = 1/4x - 7
Slope-Intercept
True or False
y = mx + b is a linear equation
True
Put into y=mx + b form first.
Then identify the slope.
4x + y = 8
-4
4x + 2y = 7
Solve for y first.
What is -2?
Is this written in slope intercept form or standard form?
Ax + By = C
Standard
Identify the y-intercept: y = 3/4x - 2
What is -2?
For y = -3x + 10, describe its graph.
Start at (0,10) on y-axis; then move 3 down and 1 to the right.
What is the x-intercept? (Hint: Put zero in for y.)
y = 1/2x + 2
(-4,0)
-6x + 3y = 9
Solve for y first.
What is 2?
Is this written in slope intercept form or standard form?
y = mx + b
Slope Intercept
Write in slope-intercept form: slope = 2; (0, 5)
What is y = 2x + 5?
What kind of line has a slope of 0?
horizontal
