Question

Write the equation of a line with slope m = 3 and including point (3, 5).

Answer 1

Just use the point slope form, where m=3, \((x_1,y_1)\)
\[y-y_1=m(x-x_1)\]

Answer 2

How do I do that?

Answer 3

Like this,
\[y-5=3(x-3)\]

Answer 4

Expand the RHS
y-5=3x-9
Add 5 to both sides to isolate y, and you're done

Answer 5

How do you "isolate" y?
