Jamal for x=0 what value you get for y ?

OpenStudy (vuriffy):

Use multiple x values to make sure it withholds all inputs to the graph. Consider: -1, 0, 1, and 2.

OpenStudy (vuriffy):

When x is 0 on the graph, y is 3. 2(0) - 3 = -3. So this proves B to be incorrect.

jhonyy9 (jhonyy9):

Jamal for x=0 than you get the right value for y and in the second case for y=0 you get the right value for x so from these two cases you can selecting the right equation of this graph sure

OpenStudy (jamaljunior):

hey i use desmos and got C as answer is this correct?

OpenStudy (vuriffy):

For the graph, when x = 1, y = 1. Let's try Option C) -2(1) + 3 = 1 Yes, C is correct.

OpenStudy (jamaljunior):
