What is the missing number? __- (-5) = -7

-12

Step-by-step explanation:

When there are two minus signs, that means it turns into a plus sign. That makes the equation x+5=-7. To solve this, you have to subtract five from both sides to get x=-12. This means that the blank is equal to -12.

Hope this helps

The missing number is -12. (-12-(-5)=-7.

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
