In Exercises 911 Write A Linear Function F With The Given Values class=

Sagot :

Answer:

f(x) = 2x + 3; f(x) = -5/2x + 9; f(x) = -x + 1

Step-by-step explanation:

to find the slopes you must use the equation (y1 - y2) / (x1 - x2)

y is the number that f(x) equals to and x is the number inside the parenthesis

the first one -->

(5 - 3) / (1 - 0) = 2

the y intercept is already given in all equations (it is the one that f(0) equals)

the equation is f(x) = 2x + 3

the second one -->

(4 - 9) / (2 - 0) = -5/2

the equation is f(x) = -5/2x + 9

the third one -->

(1 + 2) / (0 - 3) = -1

the equation is f(x) = -x + 1
