Equation of a straight line

What is the equation of the line that goes through the points (3,-1) and (2,-4)?

• y = 3x - 4
• y = -3x + 8
• y = 3x - 1
• y = 3x - 10

What would be the equation of a line that goes through the ordered pairs

(-2, 6) and (-4, 12)

• y = -3x

• y = 3x

• y = -1/3x

• y = 1/3x

What is the equation of the line?

(a)  

Find the slope and y-intercept of the two points to formulate an equation in slope-intercept form. 

(2,6)    (4,10)

• y-6 = 2(x-2)

• y-10=2(x-4)

• y=2x +2

• y = 2x -2

Write equation of the line containing 

(0, 0) and (1, 3)

• $y=\frac{1}{3}x+\frac{8}{3}$

• $y=3x+\frac{8}{3}$

• $y=\frac{1}{3}x$

• $y=3x$

Write equation of a line in slope-intercept form given...

(0,2) and (2,0)

(a)  

Given the two points: (0, 6) and (6,18), write the equation of the line in point-slope form.

Write the equation of the line through (2 , 0) and (-1 , 12)

• y=-12x+2

• y=-12x+8

• y=-4x+8

• y=-4x+2

Given two points: (4;2) and (6;3)

What is the equation of the line in point slope form?

• y - 2 = 1/2 (x - 4)

• y + 2 = 2 (x - 4)

• y - 2 = 2 (x - 4)

• y - 4 = 1/2 (x - 2)

Review Question 4b.

Write the equation of the line that passes through the points (1,-4) and (-2, 8) in point-slope form.  There are two correct answers for this problem.

•  $y-8=-4\left(x+2\right)$ 

•  $y-8=-\frac{1}{4}\left(x-2\right)$ 

•  $y-4=-\frac{1}{4}\left(x-1\right)$ 

•  $y+4=-4\left(x-1\right)$
