What are the intercepts of the line #2y=-x+1#?
The final answers are at parts ( 2 ) and ( 3 )
Before you can determine the intercepts you need to manipulate the equation so that you only have y on the left hand side of the equals sign and everything else on the other side.
To isolate y and still maintain balance multiply both sides by
Now to find the intercepts:
Step2. The graph crosses the x-axis at y=0
Substitute y=0 in (1) giving:
Multiply both sides by 2 giving:
so one of the points where it crosses is at
Step3. The graph crosses the y-axis at x=0
Substituting y = 0 in equation ( 1 ) gives:
so the other point where it crosses is at
