Standard Form, Slope Intercept Form, Vertical and Horizontal Lines

A line with 0 slope looks like...

• horizontal line

• vertical line

• slanted line

• coordinate pair

What is the y-intercept of the line with the equation y = -1/2x + 6

• (0, -1/2)

• -1/2x

• (0, 6)

• -5 1/2

What is the slope of the line with the equation 2y = 10x + 5?
(HINT: SOLVE FOR Y FIRST!)

• 10

• 5

• 5/2

• 8

x + y = 4

• y = x + 4

• y = -x + 4

• x = -y + 4

• x= y - 4

Which equation is written in STANDARD form?

• y = 1/2x + 2

• y - 3 = -5(x + 2)

• -7x + 2y = 9

• 3x + 2 = y

^{What is the x- intercept of the line?}

• (1, 0)

• (2, 0)

• ( -1, 0)

• (-2, 0)

If a line goes through the points (4, 5) and (4, 7), what type of line is it?

• Horizontal line

• Vertical line

• Slanted line

• No way to tell

Write an equation in Standard Form.
A store sells t-shirts for $12 each and sweatshirts for $15 each. You plan to spend $120 on t-shirts and sweatshirts.

• 2x + 5y = 120

• 12x + 15y = 120

• 12 + 15y = 2x

• 12x + 15 = 120

In the equation y=mx+b, what does the m represent?

• slope

• y-intercept

• linear

• point-slope

What is the y-intercept in the equation y= -2x + 5

• -2

• 3

• 5

• Cannot be Determined
