I do hope that your question has been edited in terms of your intention. To "solve ' this, it needs to be an equation; for example
`x+3y-7=0` rather than just `x+3y-7` which is simply an expression. When we calculate co-ordinates, we use the equation. In this case, it is a straight line or linear equation. We find x when y=0 and we also find y when x=0.
`therefore` when x=0: ` 0+3y-7=0` (If your equation does not equal 0 substitute the value accordingly.)
So the co-ordinates of the y-intercept (where x=0) are `(0;7/3)`
Always place the x value first.
Now do the same thing when y=0 `therefore x+3y-7=0` becomes
So the co-ordinates of the x-intercept (where y=0) are `(7;0)`
Note x always comes first.
If you were drawing the graph to form a line you can plot as follows. The line would continue but note the points (the dots) on the y-axis and the x-axis.
Ans: y intercept (0;7/3) x-intercept (7;0)
