Question

Consider the line that passes through the point (3, -6) and has a slope of 4.

Part 1: Write the equation of this line using point-slope form.
Part 2: Using your equation from part 1, rewrite this equation in slope-intercept form. Make sure to show all of your work.
Part 3: Using your equation from part 2, rewrite this equation in standard form. Make sure to show all of your work.

Answer 1

what i have so far....
Part 1:
y + 6 = 4(x - 3)

Part 2:
distribute the 4
y = 4x - 12

i don't know what to do for part 3.

Answer 2

Standard form:
\[Ax+By=C\]

Answer 3

right so would it be... 4x + 12y = C ?

Answer 4

Not quite, no. Move all the terms with x and y to one side first.

Answer 5

4x - y = 12?

Answer 6

Yep, that's it

Answer 7

thank you so much! :)

Answer 8

What? Where did the "+6" go? It was hanging out with the 'y', there, for a moment. Then, it just disappeared.
