Answer:
When x=1 the y-coordinate is 6.
Step-by-step explanation:
The given linear equation is
[tex]3x+2y=15[/tex]
We need to find the y-coordinate when x=1.
Substitute x=1 in the given equation, to find the y-coordinate.
[tex]3(1)+2y=15[/tex]
[tex]3+2y=15[/tex]
Subtract both sides by 3.
[tex]3+2y-3=15-3[/tex]
[tex]2y=12[/tex]
Divide both sides by 2.
[tex]\frac{2y}{2}=\frac{12}{2}[/tex]
[tex]y=6[/tex]
Therefore at x=1 the y-coordinate is 6.
