The points (1, 7) and (0, 2) fall on a particular line. What is its equation in slope-intercept form?
NARA [144]

Slope-intercept form is y = mx + b


So we can manage to do this:


(y - yo) = m.(x - xo)


Where (x, y) and (xo, yo) are points of this line, this way we can discover the slope.


(7 - 2) = m.(1 - 0)

5 = m

m = 5


So,


y = 5x + b


Now we still have to use (y - yo) = m.(x - xo), but this time we will put only 1 point and the slope.


(y - yo) = m.(x - xo)

(y - 2) = 5.(x - 0)

y - 2 = 5x

y = 5x + 2


So, this is the line in slope-intercept form.

(2, –2), slope is 1.4
DaniilM [7]

y = 1.4x - 4.8

the equation of a line in ' slope - intercept form ' is

y = mx + c  ( m is the slope and c the y- intercept )

the partial equation is y = 1.4x + c

to find c, substitute (2, - 2) into the partial equation

- 2 = 2.8 + c ⇒ c = - 2 - 2.8 = - 4.8

y = 1.4x - 4.8 is the equation in slope- intercept form
