Write to explain how subtracting 4/5 - 3/5 is similar to subtracting 4 -3
kondor19780726 [428]
Subtracting fractions with a common denominator, you subtract only the numerator, which are 4 and 3, and keep the common denominator the same, underneath the fraction. It is just subtracting 4 and 3 and putting them in a fraction, just like 4-3

Write an equation in point – slope form from the line through the given point with the given slope. (-10, -1); m=-1
Alexxandr [17]

Answer:

y = -x - 11

Step-by-step explanation:

We know the equation must be: y = -x + c

However we do not know what "C" is. If we plug in our x and y values then we can find out the value of C.

So:

-1 = -(-10) + c

-1 = 10 + c

so c = -11

So our equation is:

y = -x - 11
