Question

Medal(:
Write the equation of of a line with the points (2,2), (0,-2) in slope intercept form.

Answer 1

y = mx + b

Answer 2

do u know how to get the slope given 2 points ?

Answer 3

The slope is 2 right?

Answer 4

correct! :)
so, m= 2
slope intercept form : y= mx+c
now u just need the "c"

Answer 5

c is actually the y- intercept, of the form (0,c)
so 'look' at 2 points, i am sure you will be able to figure out the value of c

Answer 6

-2?

Answer 7

-2 is absolutely correct!
another way to get 'c' is to plug in any of the points,
like if i use (2,2)
2 = 2(2) + c giving c= -2

so, the equation y=mx+c , for this Q, will be
y= 2x-2
any doubts ?

Answer 8

Nope! Thanks so much!

Answer 9

welcome ^_^
