Pick the answer choice that best represents the slope and y-intercept for the following equation:

y = -x

• Slope: -1, y-intercept: -1

• Slope: 1, y-intercept: 0

• Slope: -1, y-intercept: 0

• Slope: 0, y-intercept: 0

Write the equation for the line in slope-intercept form.

• y= -1x+3

• y= 4x+3

• y=1/4x+3

• y= -4x+3

Write the equation for the line in slope-intercept form.

• y=-1x+3

• y=4x+3

• y=¼x+3

• y=-4x+3

Write the equation for the line in slope-intercept form.

• y= -1x + 3

• y= 4x + 3

• y= -4x + 3

Answer explanation

y - intercept is (0,3), so your equation has to end in +3

The slope is positive

From the y-intercept you move down -4 and left -1

-4/-1 = 4

So

y = 4x + 3

Write the equation for the line in slope-intercept form.

• y= -1x+3

• y= 4x+3

• y=1/4x+3

• y= -4x+3
