Find the equation of the line that passes throught the given point (3, -3) and which has the slope m = 2.
The easiest way to do this is to use the "point-slope" form of the equation of a line:
The equation of your line is:
Simplify.
This is the equation.
If you need the "slope-intercept" form:, then, using the given slope m = 2 and the x- and y-coordinate of the given point (3, -3):
Solve for b, the y-intercept.
Subtract 6 from both sides of the equation.
The final equation, in "slope-intercept" form is:
Answer by mukhopadhyay(490) (Show Source): You can put this solution on YOUR website!
The slope intercept form is y = mx+b;
m=2; the equation translates to y = 2x+b;
Since the line passes thru (3,-3):
-3 = 2(3) + b
=> b = -9;
Answer: The required equation is y = 2x-9
