Answer:
a. (1,14) and (7,7)
b. slope = -1.2
Step-by-step explanation:
a. Use the points that are actually on the drawn line
(1,14) and (7,7)
b. Slope formula is :

It doesnt matter which one is 1 or 2. I will take (1,14) as (x1, y1) and (7,7) as (x2, y2)

20 i think im not very sure
9+9+7+7=32 :) you add each side up
Answer:
x=5
Step-by-step explanation:
3/5(x-10)=18-4x-1
3/5x-30/5=18-4x-1
3/5x-6=18-4x-1
+6 +6
3/5x=23-4x
+4x +4x
4 3/5x=23
23/5x=23
23/5 divide , so you actually multiply both sides by the reciprocal 5/23
x=5
Answer:
16
Step-by-step explanation:
2x² - 5x - 17
Put x as -3 and solve.
2(-3)² - 5(-3) - 17
2(9) - (-15) - 17
18 + 15 - 17
= 16
