Question

Which function corresponds to the table?

Answer 1

It is c) y=-2x+3
Beacuse you just put x as in table etc. 0,1,2 and then change the y with y as in table 3,1,-1.

Answer 2

Answer: Choice C) y = -2x+3

---------------------------------------

Work Shown:

Using the slope formula, find the slope of the line through (0,3) and (1,1)
m = (y2 - y1)/(x2 - x1)
m = (1 - 3)/(1 - 0)
m = (-2)/(1)
m = -2
The slope is -2

The y intercept is 3 since x = 0 leads to y = 3 in the first row of the table
So b = 3

Plug m = -2 and b = 3 into y = mx+b
y = mx+b
y = -2x+3
