We want to find the equation of the line with given slope and y-intercept.
The slope-intercept form of a line is:
![y=mx+b](https://img.qammunity.org/2023/formulas/mathematics/high-school/smsb8cbft03lwblmi49nf2l6jby2ofxzws.png)
Where
m is the slope
b is the y-intercept (y-axis cutting point)
We are given the slope and y-intercept, so we simply substitute it. Steps are shown below:
![\begin{gathered} y=mx+b \\ y=(2)/(5)x+(-7) \\ y=(2)/(5)x-7 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/14xz8ez1rrplvzmieyauv6quboj7z1it96.png)
The equation of the line is:
![y=(2)/(5)x-7](https://img.qammunity.org/2023/formulas/mathematics/college/rcyy2sje5bt9e04nzdpay5q7kqc9ly6fa7.png)
