1.) 9(4) + 8(5)
36 + 40 = 74
2.) 2(3) + 8(3)
6 + 24 = 30
3.) 4(5) + 7(5)
20 + 35 = 55
4.) 10(4) + 18(5)
40 + 90 = 130
5.) 2 + 8(1/4)
2 + 2 = 4
6.) 9(1/3) + 8(1/4)
3 + 2 = 5
7.) 3(8) + 7(4)
24 + 28 = 52
8.) 12(1/4) + 16(5)
4 + 80 = 84
Answer:
slope = - 7
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
y - 4 = - 7(x - 6) ← is in point- slope form
with slope m = - 7
B. and D.
