Slope Intercept Form Classwork

Matt is going to create a graph of the equation y= -0.75x + 6 , which of the following statements will be TRUE about the graph?

• The graph will go through the origin.

• The graph will increase from left to right.

• The graph will cross the x-axis at (6, 0).

• The graph will have a slope of -0.75

Write the equation of the line in slope intercept form.

• y = -1/3x - 2
• y = 1/3x - 2
• y = 3x - 2
• y = -3x - 2

Jackson started with $800 in his savings account, but has to pay $30 a month for his electricity bill. Write an equation in slope intercept form that relates his savings, y, to the amount of months, x.

• y = -30x + 800

• y = 30x - 800

• y = -30x

• y = 12x - 30
