Complete the equation of the line whose slope is -2 and y-intercept is (0,3).

Answer 1

Your equation is y = mx + b

y is your output, x is your input, m is your slope, and b is the y intercept (0,b).

So if you know the slope is -2, you know the m value.

If you know the y intercept is (0,3) you also know the b value.

Your overall equation would be y = -2x + 3

You want x and y to remain in there to keep this a function/equation.
