The points are .
The point-slope form of the line equation is . where m is the slope.
First find the slope of the line.
\ (Substitute
5 for x1,
5 for y1, 4 for x2 and
2 for y2)
(Product of two same signs is positive)
(Add:
)
(Cancel common terms)
Next find the point-slope of the line equation .
(Substitute
5 for x1,
5 for y1 and
)
(Product of two same signs is positive)
(Multiply each side by 3)
(Cancel common terms)
(Apply distributive property:

The equation is .
First find the y-intercept.
\The y-intercept is the value of y, when x = 0.
\ (Substitute x = 0 in original equation)
(Additive identity property:
)
(Divide each side by negative 3)
(Cancel common terms)
The y-intercept is .
Next find the x-intercept.
\The x-intercept is the value of x, when y = 0.
\ (Substitute y = 0 in original equation)
(Multiply:
