Answer:
Answer below
Step-by-step explanation:
17. The points are (1,9) and (4,6)
y2 = 6, y1 = 9, x2 = 4 and x1 = 1
Slope m = (y2 - y1)/(x2 - x1)
Slope m = (6 - 9)/(4 - 1)
Slope m = -3/3
Slope m = -1
And the equation is
y - y1 = m(x - x1)
y - 9 = -1(x - 1)
y - 9 = -x + 1
y = -x + 1 + 9
y = -x + 10
y = 10 - x
