Given an equation with x and y and a pair of coordinate points, how do you know if the points are a solution?

• Plug them into the equation to see if they make the equation true.

• Guess.

• You will never know if it is true.

• Ask your teacher.

The location where the line crosses the y-axis is called the...

• slant

• slope

• y-intercept

• x-intercept

What kind of line is created with the equation x=3

• No line is created. It is only a coordinate point

• A curved line.

• A vertical line going through the x-axis at 3.

• A horizontal line going through the y-axis at 3.

The slope is tripled and it is shifted up 8 units.

What's the new equation?

• y = 11x - 60

• y = 4x - 28

• y = 12x - 12

• y = 12x - 28
