Question 1207294
<font color=black size=3>
Slope-intercept form is {{{y = mx+b}}}
m = slope = -2/3
b = y intercept = 3


{{{y = mx+b}}} will update to {{{y = expr(-2/3)x+3}}}


Multiply both sides by 3 to clear out the denominator. 
Then add 2x to both sides so the variable terms are on one side, while the constant is on the other side.


{{{y = expr(-2/3)x+3}}}


{{{3y = 3(expr(-2/3)x+3)}}}


{{{3y = -2x+9}}}


{{{2x+3y = 9}}} is the equation in standard form Ax+By = C
