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.
