Question

If a line with a slope of -2 crosses the yaxis at (0,3) what is the equation of the line

Answer 1

`y=-2x+3`

Explanation:

Notice that with the provided information they are given you not ust the slope of the line (-2), but also the y-intercept (the point where the line crosses the y-axis which happens when x=0).

So you can directly write the equation of the line in slope-intercept form [
`y=mx+b` where "m" is the slope and "b" the y-value when x=0].

Such gives us:

`y=-2x+3`
