Question

Write the equation of the line passing through the points (0, -4) and (-2, 2).

y = 3x - 4
y = -3x + 2
y = -3x - 4
none of the above

Answer 1

ok soooo, we want our equation to look like
y=mx+b.

Again, remember, b = our y-intercept.
That is the place where we have an ordered pair with an x value of 0.
(0,b)

Hmmm do they give us something like that in this problem?

Answer 2

no?

Answer 3

They gave us a point on the line, it passes through the point (0,-4)
On a graph it would look like this
That is where the line will cross the y-axis.

Again in the form, y=mx+b
b is where the line will cross the y-axis.

So where does the line cross the y-axis?
