Answer: Y = 3/8

Step-by-step explanation:

You can either use the rise/run method or subtract 2 points from the line to get the slope. You can do the rise/run method by starting at a point that is on the corner of the square and keep counting how many spaces you have to go until you get to the next even point. This number will be on the bottom, then count up until you get to that even point,this amount of spaces this takes will be on top. Since there are only 2 visible points on this graph,I will use the other method. You can use either the y1-y2/x1-x2 formula or do this

8,3

0,0

8,3  
Remember,the y goes on top! Our slope is 3/8,also since the y intercept is the orgin/0,0 we don't need to add it at the end. I hope this helps and wasn't too complicated!

y =  3/8(x) is the equation that represents the proportional relationship in this graph, for y in terms of x.

What is proportional?

In mathematics, two sequences of numbers, frequently experimental data, are proportional or directly proportional if their corresponding elements have a constant ratio, known as the coefficient of proportionality or proportionality constant.

If corresponding elements in two sequences have a constant product—also known as the coefficient of proportionality—then the two sequences are inversely proportional.

This definition is frequently broadened to include associated varying amounts, also known as variables.

We can see that when y = 1.5, then x = 4

And when y = 3, x = 8

Putting the value in slope form

y - y1 = m(x - x1)

3 - 1.5 = m(8 - 4)

1.5 = m(4)

m = 1.5/4

m = 3/8

Now simply we put the value in y-intercept form

y - 3 = 3/8(x - 8)

y = 3/8(x) - 3 + 3

y =  3/8(x)

Which graph represents the linear equation y equals one fourth x plus 1 on the coordinate plane?

Answers

Answer: It is the last graph you listed. y=1/4x+1 this means the slope is 1/4 and the y intercept is. The last graph matches this exact description.

Step-by-step explanation:

I believe it’s the second before last graph because the plus one in the equation represents a shift up of one unit which is represented and being that the slope (rise/run) is 1/4, it also shows how you reach the next point by running 4 units to the right and rising one unit up.

To make iced coffee, Sara puts her hot coffee into a refrigerator when it’s temperature is at 130 ℉ . The temperature of the coffee drops 4 ½ ℉ each hour. What is the temperature of the coffee after 5 hours?

PLEASE HELP I’M CONFUSED

Answers

To solve this all you need to do is multiply 4 1/2 x 5 and then subtract the Sun by 130°F. So 4 1/2×5 equals 22.5. 130-22.5=107.5. so the temperature of the coffee after five hours is 107.5°F.
If the coffee starts a 130 degrees and it cools if 4 1/2 degrees an hour and is in the fridge for 5 hours so 5 X 4 1/2 and that equals 22 1/2 so you would subtract 130 by 22 1/2 which would equal 107 1/2 degrees or 107.5 degrees

How can you use mental math and the inverse property of addition to find the sum [5.5+(-2.3)] +(-5.5 + 2.3)?

Answers

Answer:

To use mental math and the inverse property of addition to find the sum [5.5+(-2.3)] +(-5.5 + 2.3), you can use the following steps:

Rewrite the expression as [5.5+(-2.3)] +(-5.5) + 2.3.

Use the inverse property of addition to rewrite (-5.5) as 5.5, so the expression becomes [5.5+(-2.3)] +(5.5) + 2.3.

Use the inverse property of addition again to rewrite (-2.3) as 2.3, so the expression becomes [5.5+2.3] +(5.5) + 2.3.

Use the associative property of addition to rearrange the terms in the expression, so it becomes 5.5 + 2.3 + 5.5 + 2.3.

Use mental math to add the terms, which gives you a result of 15.8.

Therefore, the sum of [5.5+(-2.3)] +(-5.5 + 2.3) is 15.8.

Answers

Answer is y=6x

Explanation


When you have a graph, you can find the slope or coefficient next to x, by finding rise over run on the graph or using slope formula.

On the graph, from 0, 0, we go up or rise +6 and go right or run +1. Slope is 6/1 or 6.

Or, you have (0, 0) and (1, 6) as two definite points. Using slope formula
y2 - y1 over x2 - x1

6 - 0 over 1 - 0 = 6/1 or slope of 6.

Y=6x I think. Have a good day
