Question

Find the equation of the line passing through the points (2,11) and (-8,-19)

Y=[?]x+[ ]

Answer 1

Slope Formula: y2-y1/x2-x1

Solve:

= -19-11/-8-2

= -30/-10

= 3

Find the y-intercept using one of the coordinates.

y = 3x + b

11 = 3(2) + b

11 = 6 + b

11 - 6 = 6 + b - 6

5 = b

Final Answer: y = 3x + 5
