How would you write the equation with a slope of 2/3 and a y-intercept of -3

• y=3/2x+3
• y=2/3-3
• y=2/3x-3
• y=2/3x+3

Find the slope of a line that passes through the given points:
(1,1) and (3,4)

• $\frac{2}{3}$

• $\frac{-2}{3}$

• $\frac{3}{-2}$

• $\frac{3}{2}$

Write the equation in point-slope form of the line that passes through the given point and has the given slope.
(4, -7); m = -1/4

• y + 7 = -1/4(x - 4)
• y - 4 = -1/4(x + 7)
• y + 7 = 4(x - 4)
• y - 7 = -1/4(x - 4)

Find the equation of the line that passes through the points:

(-2, 4) and (1, 10)

• y = 2x - 1
• y = -2x + 1
• y = 2x
• y = -2x

Find the equation of the line that passes through the points:

(-3, 3) and (3, -1)

• y = -⅔ x + 1 
• y = -⅔ x  
• y = ⅔ x + 1 
• y = -⅔ x +3 

Find the equation of the line that passes through the points:
(4, -1) and (0, -3)

• y = 2x - 3
• y = -2x + 3
• y = ½ x - 3
• y = -½ x + 3
