Question

Write an equation of the line through (6,-2) with a slope of 4

Answer 1

Notice that for this question, they are providing you with:

1) The slope of the line (4)

2) a point on the plane through which the line goes (6, -2)

So you can directly use for this the "point-slope" form of a line which is as follows:

`y-y_0=m(x-x_(0))`

This includes m as the slope, and the pair (x0, y0) as the pair representing the point the line goes through.

So, let's use the info they gave you to complete this:

`y-(-2)=4(x-6)`

which we can work out a little more:

`y+2=4x-24`

And even a little more to finish the equation of the line in its standard slope-intercept form:

`y=4x-24-2=4x-26`

So the equation of the line is:

`y=4x-26`
