Hi,
I'm having trouble finding which points the line crosses the x and y axes on a graph given the following equation:
y = 4x -3
I have solved where the line crosses the y axes by replacing x with 0.
y = 4(0) -3
y = -3
However, when it comes to x this formula is not working
0 = 4x -3
3 = 4x
that's where im stuck...how can 3 = 4x when x has to be a whole number to be plotted on the graph?
Please help!
Thanks
Edit: I just realized I may be doing this problem incorrectly. I am taking Algebra through independent study and dont have the help of a regular teacher. The book I'm using doesn't provide much in the way of explanations and usually uses a very simple equation for the example provided. The example in this section is y = x - 3
so y = 0 - 3
y = -3
0 = x - 3
x = 3
when you throw multiplication into it such as with my problem it seems much more difficult to me.
If somebody knows the correct formula, please post it, thank you
