Given data:
The first equation is y=3x-5.
The second equation is y= -x+7.
The standard equation of the line is,
[tex]y=mx+c[/tex]Here, m is the slope of the line, and c is the y-intercept.
Compare the above equation with the first equation.
[tex]\begin{gathered} m=3 \\ c=-5 \end{gathered}[/tex]Compare the standard equation with the second equation.
[tex]\begin{gathered} m=-1 \\ c=7 \end{gathered}[/tex]Thus, the slope of the first line is 3, y-intercept is -5, and slope of the second line is -1, y-intercept is 7.
