Answer:
![y=2x-14](https://img.qammunity.org/2020/formulas/mathematics/middle-school/xagiaahfqtu4ivcmf4wb4v5hvroy42861r.png)
Explanation:
we know that
The equation of the line in slope intercept form is equal to
![y=mx+b](https://img.qammunity.org/2020/formulas/mathematics/high-school/8nudzfk4b5l0arb9iixag2w8am6zn99zlr.png)
where
m is the slope
b is the y-intercept
In this problem we have
![m=2\\point\ (9,4)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/j6km19a1zwx7xkavylj0tb3y83qh6jv27h.png)
substitute the given in the equation
![4=2(9)+b](https://img.qammunity.org/2020/formulas/mathematics/middle-school/igvwcc7iu3hu97pwc363ncvaour71kqjdt.png)
Solve for b
![4=18+b](https://img.qammunity.org/2020/formulas/mathematics/middle-school/axdgxz0qwhgi5hnng87rocnvspsddvjna3.png)
subtract 18 both sides
![4-18=b](https://img.qammunity.org/2020/formulas/mathematics/middle-school/iz23cq0jrvhm5irkzucdte21z7zzlkbmt4.png)
![b=-14](https://img.qammunity.org/2020/formulas/mathematics/middle-school/hturm8e8seoykibrqv2ka1qn048vfk0cno.png)
therefore
The linear equation in slope intercept form is equal to
![y=2x-14](https://img.qammunity.org/2020/formulas/mathematics/middle-school/xagiaahfqtu4ivcmf4wb4v5hvroy42861r.png)
