Answer:
10
Step-by-step explanation:
Formula for slope: (y2-y1)/(x2-x1)
Plug the numbers in: (-10-(-20))/(-7-(-8))=10/1=10
Slope is 10.
Answer:
The slope-intercept form of the given equation is,

Step-by-step explanation:
The given equation of the line is,
- 4<em>x</em> + 7<em>y</em> = - 14
Adding '4<em>x</em>' on both sides of the above equation, we get
- 4<em>x</em> + 7<em>y</em> + 4<em>x</em> = - 14 + 4<em>x</em>
⇒ 7<em>y</em> = 4<em>x</em> - 14
Now, dividing both sides of the above equation by '7', we get
7<em>y</em> ÷ 7 = (4<em>x</em> - 14) ÷ 7


This is the required equation of the line in slope-intercept form.
GCF means: greatest common factor, the biggest number by which both numbers can be divided.
We knew that both numbers are divisible by 3: both 6 and 3 are divisible by 3.
also, they are both divisible by "a": since they are products of a and other numbers or variables.
So the answer is:
3a
Yup it is C. Integers and Positive Integers are under positive numbers so it has to be, becuase B is wrong.
