which of the following points are on the line given by the equation y=4x+2?

Question

geerky42 · Answer

One of the ways to solve it is plugging in x value then solve for y and see if it matches

anonymous · Answer

well my options are 
a. -2,-6
b. 1,6
c. -2,-10
e. 3,14

the options are points given in (x, y) form
what geerky42 is saying is that you can plug in each option to see if it works :)

for example (-2, -10) into y=4x+2
would give  -10 = 4(-2) + 2    then simplify
                 -10 = -8 + 2
                 -10 = -6
but -10 doesn't equal -6    so  (-2, -10) would not work

btw are you sure that is the correct question?
because then there would be 3 out of the 4 options that work o-o

yeah it's the right one haha i tried option b
so 6= 4(1) + 2
6=6
so would option b be the right answer

B is right.. from the orig problem y=4x+2 the "2" is the y-intercept which is where the the line crosses the Y axis (its a positive 2) and the 4 is where it crosses the X axis so just draw a line thru those 2 numbers on each axis and then plot the points and see what falls on the line I dont have any graphing paper but if im not mistaken (1,6) should be the only point that falls on the line---- I think i did that right ;)
