Write the equation in slope-intercept form to represent the line that is graphed.

• y = 1/2x + 1

• y = -2x -2

• y = 2x +2

• y = 2x - 2

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=¼x+3

• y=-4x+3

Write an equation of the line in slope intercept form that passes through the point (3, 5) and has the given slope 4.

​ (a)   = ​ (b)   ​ (c)   ​ (d)   ​ (e)  

• 4

• x

• -

• y

• 7

• +

• 3

• 5

• 12

Type the equation in slope-intercept form of a line with the given slope and y-intercept.
