[tex]\underline {Find \ Slope:}[/tex]
[tex]\boxed {Slope = \frac{3-(-6)}{3-(-6)} = \frac{9}{9} = 1}[/tex]
[tex]Substitute \ slope \ into \ the \ general \ equation: \bf y = mx + c[/tex]
[tex]\boxed {y = x + c}[/tex]
[tex]\underline {Find \ y-intercept: }[/tex]
[tex]At (3, 3), [/tex]
[tex]3 = 3 + c[/tex]
[tex]c = 3 - 3 [/tex]
[tex]\boxed{c = 0}[/tex]
[tex]Substitute \ into \ equation, \ \bf y = x + c[/tex]
[tex]\boxed {\boxed {y = x}}[/tex]
