Hello, I'm here for another related intercept form problem of the formula: \(\displaystyle \displaystyle \frac{x}{a} + \frac{y}{b} \:=\:1\)

a) Find the equation of the line passing through (-5,-7) AND with y-intercept 3.

b) Find the equation of the line passing with x-intercept 1/3 and y-intercept 2/5.

I'm not sure how this solution will be, I need this as my reference pattern.

Thank you.

Note: In letter B I couldn't figured since its a fraction and the way of having an LCD might be unsure of the correct equation so really need an informative information.

Also in Letter A, we don't have an example related for that.
