Answer: -2
Step-by-step explanation: The line has a slope of -2/1, which is just -2.
For find f(-2) of f(x)=7x+3, plug in -2 for x.
7(-2)+3=y
-14+3=y
y=-11
To find the rate, or the slope, you divide x/y. So 2/6 is 1/3. 3 over 9 is also 1/3. So the rate is 1/3. In rates you always divide, you don't mulitply or subtract or add to find the rate.
Answer:
Mark C.
Step-by-step explanation:
If there are 27 students in both classes, it's logicial to multiply both classes by two to get the total students.
Since the <em>S</em> stands for the students absent, that should come after the brackets.
9c + 5ab/ 11c is the simplified answer
The graphs have the same slope (2) and are parallel
The difference is the y intercept
y = 2x has as y intercept of 0
where y = 2x-7 has a y intercept of -7
