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, 0.4 for y1,
1 for x2 and
2 for y2)
(Subtract:

Next find the point-slope form of the line equation .
(Substitute 5 for x1, 0.4 for y1 and
)
(Apply distributive property:
)
(Multiply:
)
(Subtract y from each side)
(Apply additive inverse property:
)
(Add 2 to each side)
(Apply additive inverse property:
)
(Add:

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)
(Multiply:
)
(Apply additive identity property:
)
(Multiply each side by negative one)
(Product of two same signs is positive)
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)
(Apply additive identity property:
)
(Divide each side by 0.4)
(Cancel common terms)
(Divide:
)
The x-intercept is .
The x-intercept is and the y-intercept is
