WILL GIVE BRAINLIEST!!! How would you graph Y = -2X? Explain from beginning to end.

Mathematics

4 0

Step-by-step explanation:

Since there is no y-intercept, you start at the origin (0, 0)

The slope tells us that for every two units it goes down, it also goes one unit to the right

We know this because slope is rise/run (in this case -2/1) and the slope is negative, meaning that it starts higher up at the left and goes down towards the right.

To graph, start at (0, 0) and go down 2 units to get (0, -2) and then to the right one unit to get (1, -2)

That is the first point

Continue doing this

(1, -2) -> down 2 and to the right 1 -> (2, -4)

Alternatively, plug in values for x

y = -2(1) -> y=-2

When x=1, y=-2

And keep repeating until you get a good idea of what the line looks like

What is -0.8 as a fraction?
stira [4]

Answer:

-\frac{4}{5}

Step-by-step explanation:

There is not much that can be done to figure out how to write 0.8 as a fraction, except to literally use what the decimal portion of your number, the .8, means.

Since there are 1 digits in 8, the very last digit is the "10th" decimal place.

So we can just say that .8 is the same as 8/10.

The fraction is not reduced to lowest terms. We can reduce this fraction to lowest  terms by dividing both the numerator and denominator by 2.

Why divide by 2? 2 is the Greatest Common Divisor (GCD)  or Greatest Common Factor (GCF) of the numbers 8 and 10.

So, this fraction reduced to lowest terms is  4/5

So your final answer is: 0.8 can be written as the fraction 8/10 simplified to 4/5
