Find the slope of the line that passes through:<br> (-4,7) and (-6, -4)
Yuri [45]

Answer:

\frac{11}{2} or 5.5

Step-by-step explanation:

In order to find the slope of a line using two points on a graph, you must use

y_2-y_1/x_2-x_1

Pluging in the points (-4,7) and (-6, -4) to the formula you will get:

\frac{-4-7}{-6+4} =\frac{-11}{-2} =5.5

The equation for the line would be \frac{11}{2}x+29

What is f(–3) for the function f(a) = –2a2 – 5a 4?
Setler79 [48]
F(-3)
f(a) = -2a² - 5a + 4

Substitute a with its value, -3

f(-3) = -2(-3²) - 5(-3) + 4
f(-3) = -2(9) + 15 + 4
f(-3) = -18 + 19
f(-3) = 1

the value of f(-3) is 1.

Keith collected the names and ages of all of his classmates and organized them in the ordered pair (name, age).
erastova [34]

Answer:

It is both a relation and a function.

Step-by-step explanation:

Keith collected the names and ages of all of his classmates and organized them in the ordered pair (name, age).

Here, if we consider the name as the input and age is the output, then each and every different input there is a single output.

Because a single person can not have more than one age.

Therefore, it is both a relation and a function. (Answer)
