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 = 1/4(x - 4)

• y - 7 = -1/4(x + 4)

Which graph does NOT pass the vertical line test?

• Graph 1
• Graph 2
• Graph 3
• Graph 4
