Answer:

[tex]a=\frac{y-d}{x}[/tex]

Explanation:

To solve for a in the the equation

[tex]y=ax+d[/tex]

we first subtract d from both sides to get

[tex]y-d=ax+d-d[/tex][tex]y-d=ax[/tex]

Finally,

[tex](y-d)\div x=\frac{ax}{x}[/tex][tex]\frac{y-d}{x}=a[/tex]

A bit of rearranging gives

[tex]a=\frac{y-d}{x}[/tex]
