Question

Choose the equation below that represents the line that passes through the point (−2, −1) and has a slope of 5.

y − 1 = 5(x − 2)
y + 1 = 5(x + 2)
y + 2 = 5(x + 1)
y − 2 = 5(x − 1)

Answer 1

will give medal

Answer 2

Use the point-slope formula.

\(\sf y - y_1 = m(x - x_1)\)

Where \(\sf m\) is the slope and \(\sf (x_1, y_1)\) is a point on the line.

Can you plug in the given information into the formula?

Answer 3

y-1=5(x-2) ?

Answer 4

Not exactly.

Remember, we have (-2, -1), not (2, 1)

\(\sf y - (-1) = 5(x - (-2)\)

Can you simplify that?

Answer 5

OHH

Answer 6

It turns into positive instead of negative?

Answer 7

Correct!

Answer 8

So what do we have?

Answer 9
