Question

write the equation of the line passing throught the points (-3, -8) and (-6, 2) in slope-intercept form

Answer 1

y=-10/3x-18

Answer 2

how is it -18?

Answer 3

y=mx+b is the equation of a line.

in order to find the value for 'm', you can use the handy-dandy equation '(y[1] - y[2])/(x[1] - x[2])'

10/-3 is your value for m, in this case.

Now that you know this, you can plug in one of the two pairs of co-ordinates to solve for 'b'.

y=(-10/3)x+b
-8=(-10/3)(-3)+b
-8=10+b
0=10+8+b
-b=18
b=-18.

So, you would have 'y=-10/3x-18'

Answer 4

is lx-7l the same thing as (x + 7)?

Answer 5

and if you want put it in slope-intercept form. it could be y+8=-10/3(x+3) or y-2=-10/3(x+6)

Answer 6

ok
