Question

Given the equation y= -3x + 2.5 . When x is 0, what value of y makes the equation true?

Answer 1

Answer:

2.5

Step-by-step explanation:

plug in 0 where x is in the equation to find y

y = -3x + 2.5

y = -3(0) + 2.5

y = 2.5

check it by subbing 2.5 into the y values

2.5 = -3x + 2.5

-2.5. -2.5

0 = -3x

+3x

3x = 0

x = 0
