Question

Line n passes through the points (5,-5) and (10,-2). What is the equation of the line n.

Answer 1

Answer: y=3/5x-8

Step-by-step explanation: Use the formula (y2-y1)/(x2-x1) to find slope. (-2-(-5))/(10-5) equals 3/5, which is the slope. The equation is now y=3/5x+b. Plug in 5 for x and -5 for y to find b. -5=(3/5)(5) so -5=3+b. B=-8.

Answer 2

Answer: y = 3/5x - 8
