First, we need to know the equation of the line
![y=mx+b](https://img.qammunity.org/2023/formulas/mathematics/high-school/smsb8cbft03lwblmi49nf2l6jby2ofxzws.png)
m is the slope
b is the value of y-intercept
in the first equation
![-2x+y=3](https://img.qammunity.org/2023/formulas/mathematics/college/4uvpic0kyhrp2je3ulrpuxjvyamt4m1ryk.png)
we need to clear y in order to have the same form of the equation of the line
![y=2x+3](https://img.qammunity.org/2023/formulas/mathematics/high-school/30zzxuyb9lxdanrb1oj8xocd58463jib7b.png)
m=2
b=3
in the second equation, we do exactly the same
![\begin{gathered} -x+4y=12 \\ 4y=x+12 \\ y=(1)/(4)x+(12)/(4) \\ y=(1)/(4)x+3 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/aktk1i58b9b8vo04xz8dtrtfqpxjct3n54.png)
m=1/4
b=3
