Which of the following equations is in slope-intercept form?  y – 2 = 4( x + 3 )y – 2 = 4( x + 3 )  y = 2x + 4y = 2x + 4  y – x = 4y – x = 4  x = 3y - 7x = 3y - 7

Great Job! You remembered that an equation in slope- intercept form is going to be in the form of y = mx + b

Sorry, that’s incorrect  Remember that slope intercept form is written as y = mx +b Try Again

Identify the slope in the following equation: y = x - 3  m = 1m = 1  m = 3m = 3  m = -1m = -1  m = - 3m = - 3

Great Job! You remembered that if there is no coefficient in front of the x, then the slope is 1.

Sorry, that’s incorrect  Remember that slope- intercept form is written as y = mx +b, with the m representing the slope. Try Again Hint: sometimes there won’t be a coefficient in front of the x. That means that there is only 1 x. What might m equal then?

Identify the y-intercept in the following equation: y = (1/2)x + 4  b = 1/2b = 1/2  b = 1b = 1  b = -4b = -4  b = 4b = 4

Great Job!  You remembered that the b in slope-intercept form represents the y-intercept

Sorry, that’s incorrect  Remember that slope intercept form is written as y = mx +b, with the b representing the y- intercept Try Again

Identify the equation that matches the following graph:  y = 3x + 2y = 3x + 2  y = 2x + 3y = 2x + 3  y = 3x – 2 y = 3x – 2  y = 2x - 3y = 2x - 3

Great Job! You were able to identify the lines slope and y-intercept and identify the equation with the same information.

Sorry, that’s incorrect  Remember that slope intercept form is written as y = mx + b, m represents the slope and b represents the y-intercept. Try Again

Fantastic Job!!  You finished! Credits
