Answer:

Explanation:

The point-slope form of a linear equation is:

y− y1 =m ( x − x1 )

In this form, m is the slope of the line, and (x1 , y1 ) is a point on the line.

For the equation

y=3x−4, the slope (m) is 3, and the line passes through the point (0, -4) since the y-intercept is -4.

So, the point-slope form for this equation is:

y− (−4) = 3 (x−0)

Simplify:

y + 4 = 3x

This is the point-slope form for the equation

y = 3x −4.
