Given the linear equation y = 4x + 2, find the ycoordinates of the points (2, ), (1, ), and (3, ). Please show all of your work. Plot these points and graph the linear equation.

to get the ycoordinates, we just substitute the value of the xcoordinates given.
at x = 2:
y = 4x + 2
y = 4(2) + 2
y = 8 + 2
y = 6
thus (2, 6)
at x = 1:
y = 4x + 2
y = 4(1) + 2
y = 4 + 2
y = 6
thus (1, 6)
at x = 3:
y = 4x + 2
y = 4(3) + 2
y = 12 + 2
y = 10
thus (3, 10)
to plot this, you locate all the points we solved above. then connect these points and extend on both ends.
hope this helps~ :)
