What is the x-intercept for the given graph?

• 1

• -2

• 2

• 1/2

When you graph a line using slope-intercept form (y=mx+b), you graph the ___________ first and then use the ___________ to find the second point.

• origin; slope

• slope; y-intercept

• y-intercept; x-intercept

• y-intercept; slope

Answer explanation

The slope is 3 and the

y-intercept is (0,-4)

Plot the y intercept then use the slope to go up 3 and right 1 from the point plotted.

This point now is (1, -1)

What do you do first to graph a line from slope-intercept form?

• Use b to make the y-intercept

• Use m to make the y-intercept

• Use b as the slope to make the next point

• Use m as the slope to make the next point

What do you do second to graph a line from slope-intercept form?

• Use b to make the y-intercept

• Use m to make the y-intercept

• Use b as the slope to make the next point

• Use m as the slope to make the next point

Which equation represents the following graph?

• y = 3x + 2

• y = -2x + 3

• y = 2x + 3

• y = -3x + 2

Find the equation of the line in slope-intercept form.

• y = - 1/4x - 3

• y = 1/3x + 3

• y = - 1/4x + 2

• y = 1/3x -3

In the following equation, what is the y-intercept?  
y = -3x + 7

• -3

• 7

• -3/7

• 3
