Question

Using the equation y = 3x – 5, what would the output be for an input of -4?

.3
-17
-7
-3

Answer 1

y = 3x - 5.....input values are x and output values are y

so if your input (x) is 2.....sub 2 in for x and find your output (y)

y = 3x - 5

y = 3(2) - 5

y = 6 - 5

y = 1 <--- your output

Answer 2

y = 3x -5
= 3(-4) - 5
= -12 - 5
= - 17
The answer is ( - 17 )
