Which linear equation is represented by the table? X-2 136
Y 7 4 2-1

A. y = -x + 5
B. y = 2x - 1
c. y = x + 3
D. y = -3x + 11

A

Step-by-step explanation:

Find the rise over run (gradient) between two points. Choosing x=-2 and x=1 we get (1 - - 2) / (4 - 7) = -3/3 = -1. This means that m in y=mx+c is -1 so it is either A or C. If we then try a pair of x and y with y = -x + c we can get c. Using the first pair: 7=-1*-2+c = 2 + c so c = 5, leaving us with y = -x + 5.

Alternatively try all 4 with the numbers, if plugging in that value of x gives you that value of y then it is the correct equation.

range is infinite on both x and y axis positive and negative
