Slope and Graphing Equations of Lines

Write the equation of the line with slope -2 through the point (7, −1).

• y = −2x + 15

• y = −2x − 15

• y = −2x + 13

• y = −2x − 13

Given that the slope is  -4 and the y intercept is -4 what is the equation of the line?

• y = 4x - 4
• y = -4x - 4
• y = -4
• y = -4x + 4

Write the equation of the line with a slope of 2/3 that goes through the point (-6,10).

Find the equation of the line that has a slope of 3 and passes through (-4, 1).

• y = 3x - 11
• y = 3x + 13
• y = -4x - 13
• y = x + 11

What is standard form of a line?

• y = mx + b

• Ax + By = C

• y - y1 = m(x - x1)

• y = Ax + By

Which equation is written in STANDARD form?

• y = 1/2x + 2
• y - 3 = -5(x + 2)
• 7x + 2y = 9

• 3x + 2 = y

Put this into standard form:

y = 3x + 2

• y + 3x = 2

• 3x + y = 2

• 3x - y = -2

• 3x - 2y = 2

Parallel Lines never intersect because...

• they have the same slopes. 
• they have the same y-intercept.
• they have different slopes.
• they have different y-intercepts.
