jack1 · Answer

sub in x=15 to the given equation
so y = 46... is that what you were asking?

this is the question... im totally confused!

@hlee0919 you get this one??

jack1 · Answer

you lost me, you've got a linear equation there (y = mx + c)
so from there you can use the equation to work out any corresponding y value from a given x value...
other that that, i'm out, sorry...

@Jack1 its okay!! thanks for trying to help

anonymous · Answer

uts just 46. it
's predicting that when you input 15, you output 46. 46= 1+3(15)
