Answer:
[tex]4x+7y=49[/tex]
Step-by-step explanation:
If you don't want to go through the slope-intercept form, you can easily see that two parallel line have their x and y coefficients in the same ratio, in our case 4:7. Let the new line be, then, [tex]4x+7y=k[/tex] and state that passes through our point: [tex]4(7)+7(3) = k \rightarrow k=49[/tex]
