You can
put this solution on YOUR website!point-slope form:
y-y1 = m(x-x1)
(x,y) is a point on the line; m=slope
find two points on the line, use the slope formula to find the slope.
slope formula:
y2-y1 / x2-x1
the product is your slope (m).
choose one of the points to use in your equation, and simply plug in the numbers.
EXAMPLE:
points: (-2,0) (0,4)
4-0 / 0+2
m=4/2
now choose one of the points, and plug-in your numbers.
y-y1=m(x-x1)
i'll choose (0,4)
y-4=4/2(x-0)
which would simplify to:
y-4=4/2x
hope you understand...have fun
