Write a linear function f with the values f (2) = 4 and f(-7) = 9. I think its -5/9+5 1/9 but im not sure, help?

f(x)=-5/9x+46/9

Step-by-step explanation:

Find the coordinates:(2,4)(-7,9)

Find the slope:

m=-5/9

Find the y-intercept:

b=46/9 (or 5 1/9)

Put it together:

You get f(x)=-5/9x+46/9

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
