Question

Which equation, in point-slope form, passes through (-2, 4) and has a slope of 3?

Answer 1

Answer:

y=-2-3x

Step-by-step explanation:

Point-slope form: y-y1=m(x1-x)

In this problem, -2 is x1 and 4 is y1.

As always, m is the slope: 3.

Hence, plug these values into the equation.

y-4=3(-2-x)

Distribute the 3: 3(-2-x)= -6-3x

Now we have y-4=-6-3x

Because we want the y by itself, add 4 to each side of the equation.

y-4=-6-3x

  +4 +4

    y=-2-3x
