Answer:
question 9
92/11 or 8.36
Step-by-step explanation:
angle on straight line is 180
:. 10x+1 + 12x-5 = 180
collect like terms
10x+12x = 180+5-1
22x = 184
divide both sides by the coefficient of x
22x/22 = 180/22
:. x = 180/22(to d lowest form= 92/11)
or 8.36
Answer: 2
Explanation: the slope = rise/run. so if u have two points on the line, count how much it goes up and down divided by how much it goes left and right. so the line goes up 2, left 1, so the slope is 2/1 or 2.
hope this makes sense!
