Given the linear equation y = 4x + 2, find the y-coordinates of the points (-2, ), (1, ), and (-3, ). Please help? I am not understanding solving equations pertaiing to graphs.

Question

myininaya · Answer

just plug in 
what is y if x=-2
y=4(-2)+2=-8+2=-6
(-2,-6)

anonymous · Answer

Plug in the "x-values" given, and solve for the y value.

myininaya · Answer

you can do the rest

anonymous · Answer

what do I need to do with  -2 1 & -3

anonymous · Answer

Plug those values in for x in the y=4x+2 equation.  myininaya gave an example above.

anonymous · Answer

so use three different equations x =-2, x=1, x=-3?

myininaya · Answer

use the same equation y=4x+2
(-2, ___)
-2 is your input find out what your output y is put pluggin in -2 where that x is
y=4(-2)+2=-8+2=-6
(-2,-6)

anonymous · Answer

i got that part. I am asking to also plug 1 and -3 in for the place of x?

myininaya · Answer

ok just do as i did above

myininaya · Answer

just put that 1 where x is and evaluate y
