Find the slope of the line that passes through
(1, -19) and (-2, -7)

• -4
• 4
• 1/4
• -1/4

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)
