Answer:
18:6
Step-by-step explanation:
Since there are 18 pens and 12 are blue you just subtract 12 from 18 and get 6 and that is the answer
Answer:
The value will satisfy the equation.
Step-by-step explanation:
Given equation is . We need to find the value of
Step-1: Multiply both sides by
Step-2: Divide both sides by
So, we get after simplifying the equation.
Answer:
y-2=2(x-1)
Step-by-step explanation:
Pick any two points from the line (example: (1,2) and (2,4))
Find the slope of them
Reminder: Slope is changes in y/changes in x or y2-y1/x2-x1
In this case, m= 4-2/2-1 which is 2
Now to use slope point form, chose any point and substitute it into this equation:
y-y1=m(x-x1)
Substituting it would get
y-2=2(x-1)
Or
y-4=2(x-2)
Slope is rise over run which is -4/15
