Answer:

20=2(10)

Step-by-step explanation:

10:20 is a good point that passes a line to another.

This graph is a linear graph.

The linear equation is

y=mx+b

y = 20 (the y coordinate in the graph)

m = slope

x = 10 (the x coordinate in the graph)

b = y-intercept

<u>Finding slope</u>

To find the equation, we'll need to plug in the values in the formula. To find slope using two points, use the formula, then plug in the values:

\frac{y_2-y_1}{x_2-x_1}

(10, 20) and (20, 40)

=\frac{40-20}{20-10}

= \frac{20}{10}

\bold{m= 2}

<u>Finding the y-intercept</u>

You have to find the slope first before finding the y-intercept. So, plugin one of the two points we used to find the slope into the formula and solve for b

(10, 20)

20=2(10)+b

20=20+b

20-20=20-20+b

\bold{b=0}

The y-intercept is zero, and when it is, you do not add it since zero is nothing.

The equation is 20=2(10)

39/250 in simplest form
OleMash [197]
Getting the simplest form of a fraction is the same with getting its lowest term. Reducing fractions to its lowest term is a very simple thing to do. Here's how to simplify fractions:

There are two ways in simplifying fractions. The first method is to equally divide both numerator and denominator which results to only whole numbers. Getting the GCF (Greatest Common Factor) or GCD (Greatest Common Divisor) is the second method.

As to the fraction above, 39/250, the second method is applicable.
Let us get the GCF of 39 and 250
39= 1,3,13,39
250= 1, 2, 5,  10, 25, 50, 125, 250

Therefore, the GCF of 39 and 250 is 1. We can conclude then that 39/250 is already on its simplest form thus;
  <u>39</u>  ÷     <u>1</u> is equal to     <u>39</u>
 250       1                       250
