Question

find an equation of the line that has a slope -2 and passes through the point 10,-9

Answer 1

y-y1= mx(x-x1)

Answer 2

do you know the equation of a line that passes thru the origin (0,0) that has a slope of -2?

Answer 3

write an equation in slope intercept form that has points (5,6) (6,8)

Answer 4

you seem to just want to use this site as a free answering service ...

Answer 5

no I`m just stuck on these two

Answer 6

ok, then can you show us what youve tried so far? its prolly something minor that you may be overlooking

Answer 7

is the formula y+mx+b=x

Answer 8

almost:

y = mx+b , looks better to me

Answer 9

thanks

Answer 10

your welcome, anything else?

Answer 11

no

Answer 12

k, good luck :)

Answer 13

write the equation of the line that passes through the points (5,6) and (6,8). Rewrite in slope intercept form

Answer 14

someone help me please

Answer 15

You need the equation y = mx + b right?

First, we find what m is. I'm sure you know m = (y2 - y1)/(x2 - x1)

= (8 - 6)/( 6 - 5) = 2 ( =m)

So pick one of the points say (x,y) = (5,6) and plug in y = mx + b to find b

That is 6 = 2(5) + b

So that 6 = 10 + b and b = -4

Finally, the equation is y = 2x - 4


Hope this helps!
