Y = -3x + b
Plug in points
4 = -3(-2) + b
4 = 6 + b, b = -2
Solution: y = -3x - 2

-6 + -4 + 3 = ? Adding integers
n200080 [17]

Step-by-step explanation:

Hey there!

Here,

=  - 6 + ( - 4) + 3

While working with them remember some rules;

  • (-) + (-) = sign (-) but add them.
  • (+) + (+) = sign (+) and add.
  • (+) - (+) = subtract but keep sign of greator number.
  • (-) -(-) = subtract and keep the sign of greator number.

Likewise in your question,

=  - 6 - 4 + 3

=  - 10 + 3

=  - 7

Write the equation of the line that has the slope m=2/5 and passes through the point ​(25​,−9​). Write the equation in​ slope-in
klemol [59]
You're given the slope of the line and a point thru which the line passes.  So it makes sense to use the point-slope form of the equation of a straight line:  if the point is (a,b) and the slope is m, then 

y-b=m(x-a).  You'd then solve this for y to obtain the equation in slope-intercept form.

On the other hand, if you're asked to write the equation in slope-intercept form, starting with the general form of this equation may be faster:  y=mx+b.

Substitute the given values for x and y (which are 25 and -9) and m (which is (2/5).  Solve the resulting equation for b (the y-intercept).

Then write the finished equation:  y=( ? )x + b, where b is the y-intercept you've just found.
