What equation represents a line that when if graphed, passes through the points (0, -1) and

1 answer:

5 0

Y= 2x-1
Explanation: First, you find slope. If the first point it x-axis point is 0 and the second x-axis point is 1 then you already know the answer is over 1, so you have to figure out how many up you are going on the y-axis from -1 to 1. Which is 2, so your slope is 2/1 or just 2. Next, you find your y-intercept, which is where the line crosses the y-axis, and the easy way to find this is finding what y is equal to when x is equal to 0, in the problem you are told (0, -1) as a point, so they gave you your y-intercept right there, which is -1. Finally you right the equation in slip intercept form (y= mx+b) which is y= 2x-1

What is a way to write 100,000 using exponents?

Helen [10]

ANSWER

$100,000=10^5$
EXPLANATION

We want to write 100,000 using exponents.

This means that, we want to write 100,000 as an index number, that is a certain number raised to a certain index or exponent.

The exponent tells us how many times that number multiplies itself to give 100,000

$100,000=10 \times 10 \times 10 \times 10 \times 10$

Since 10 multiplies itself 5 times to give 100,000, we write

$100,000=10^5$
