If these two lines are parallel, they would have the same gradient.
Since Gradient = Rise / Run,
8 / -12 : -4 / 1
These two ratios are obviously not the same, so we can conclude the lines are not parallel.
To work out 10% you divide it by then. 10% of 30 is 3. To get 80% from 10%, you times it by 8. 3X8=24
Answer:
y=3x-1
Step-by-step explanation:
Pick any x and y point (the x and y needs to be next to each other)
I will choose (-5,-16) and (-2,-7)
The answer would be C because the inequality is greater than 70 but less then 80.
