Write a linear function f with f(5)=7 and F(-2)=0.

Answers

Answer:

f(x)=x+2

Step-by-step explanation:

Slope= (7-0)/(5-(-2)) = 7/7 = 1

Y-intercept= 2

substitute the slope, 1, for m and the y-intercept, 2, for b to get:

f(x)=x+2

hope this helps!

The linear function f with f(5)=7 and F(-2)=0 is f(x) = x + 2

f(5) = 7

This means when x = 5 , y = 7

(5, 7)

f(-2) = 0

(-2, 0)

This implies when x = -2 , y = 0

Using the linear function formula,

y = mx + b

where

m = slope

b = y-intercept

Therefore, the function can be represented as follows:

m = 0 - 7 / -2 - 5 = -7 / -7 = 1

Therefore,

y = x + b

0 = -2 + b

b = 2

The function in relation to x can be represented as follows:

f(x) = x + 2

Answer:

A and C are correct

Answer:

The slope is negative and it is also proportional (A and C)

Step-by-step explanation:

I used process of elimination.

If you look at the graph you will realize that x is positive and y is negative. Most times this will mean that the slope is negative, since positive and negative = a negative.

You can also tell that the y-intercept is not -3 because the line never intersects at -3 for the y line.

The relationship is proportional it goes through the origin and is also a straight line.

However, for the -6 slope, I can't really see the graph well, so I can't tell what the coordinate points are. If you can tell me, I can edit my answer and help.

Answers

Answer:

y = 60x + 40

Step-by-step explanation:

It is in the form of

y = mx + b

m is the slope

b is the y intercept.

The y intercept is 40, so it will be y = mx + 40.

The slope is 60, so y = 60x + 40!
