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)

Write the equation in point-slope form of the line that passes through the given point and has the given slope:
 (-2, -1); m= -3

• y + 1 = -3(x - 2)
• y + 1 = -3(x + 2)
• y - 1 = 3(x - 1)
• y + 2 = -3(x + 1)

What is the point given in the following equation?
y-2= 3(x+1)

• (1,3)
• (-1,2)
• (1,-2)
• (-2,1)

What is the slope (m) of the linear graph?

• 4

• -3/4

• 4/3

• 3/4
