The equation, y=4x+15 represents the relationship shown in the graph.
Finger [1]3 years ago

Answer:

4. -4x+y=15

Step-by-step explanation:

We have been given a graph of a linear function and we are asked to find the correct equation representing the relationship shown in the graph.

Since we know that the standard form of an equation is in form: Ax+By=C, where A, B and C are integers.

First of all we will find the slope of our line and write equation of line in slope-intercept form. Then we will change it into standard form.

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

m=\frac{23-15}{2-0}

m=\frac{8}{2}=4

Slope of our line is 4. We can see that y-intercept (b) is 15. Now let us write equation of our line in slope-intercept form.

y=mx+b

y=4x+15

Now we will change our given equation into standard form by subtracting 4x from both sides of our equation.

-4x+y=4x+15-4x

-4x+y=15    

Therefore, the equation -4x+y=15 represents the relationship shown in the graph in standard form and 4th option is the correct choice.

Fernando needs a total of 6
Fantom [35]

Answer:

Equation: 6f = 5

Result: 6/5 cup of flour is needed for each batch of bread

Step-by-step explanation:

Given

6 cups of flour makes 5 batches of bread

Required

His much flour is needed for each batch.

Let f represent a cup of flour.

The statement "total of 6 cups of flour to make 5 batches of bread." means that

f + f + f + f + f + f = 5 batches of bread

f * 6 = 5

6f = 5

The above equation will give the number of cup needed for 1 batch of bread.

To do that, we simply divide both sides by 5

6f/5 = 5/5

6f/5 = 1

Hence,

The equation is represented by: 6f = 5

And the result is: 6/5 cup of flour is needed for each batch of bread
