Answer:
y= -x+5
Step-by-step explanation:
We can see that everytime x increases by 1 y decreases by 1
therefore the slope is -1
to solve for b, or the y intecept, plug in a coordinate
(1,4) for example
4= -1*1+b
4= -1+b
b=5
Therefore the equation is
-x because x increases by 1 and y decreases by 1
-1/1 = -1
-1x+b = y
b is y intercept. when x is 0, is the y intercept. in the table x = 1 for the first row. subtract 1 from that value and add 1 to the y value. you get the y intercept, 5. so, y= -x + 5
