What is the slope and y-intercept from the table below?

Mathematics
1 answer:
Nataliya [291]2 years ago
4 0

Answer:

The equation is y = -5x + 55

Slope = -5

y-intercept = 55

Step-by-step explanation:

The given table shows the different coordinates of points on a straight line.

The general equation of a line is y = mx + b

where m is the slope and b is the y intercept.

Actually , here only 2 values are needed but there are 4 values                       given which is just to check whether our line is correct or not.

Substitute values of x and y in the equation.

Put (1,50),

50 = m + b    ----------(1)

Put (2,45),

45 = 2m + b    -----------(2)

Solve (1) and (2),

Slope , m = -5

y-intercept , b = 55

Hence , the equation is y = -5x + 55.

A playground is rectangular with a length of 24 miles. If the area of the playground is 812 square miles, what is its width? Ans
soldi70 [24.7K]

Answer:

33(5/6) sq miles

Step-by-step explanation:

Area = LxW

812 = 24xW

Divide by 24

W = 33.8333333 ( 33 (5/6)

8 is non repeating

3 is repeating

For nominator subtract the non repeating    (83-8 = 75)

For  denominator :  one 9 for each non repeating,one zero for each repeating (only 3 is repeating,then one zero)

  75/90  = 5/6

C=2(y-k) solve for y​
marshall27 [118]

Answer:

\blue{y = \dfrac{C + 2k}{2}}

Step-by-step explanation:

C = 2(y - k)

C = 2y - 2k

C + 2k = 2y

\dfrac{C + 2k}{2} = y

y = \dfrac{C + 2k}{2}

Match the situation to the most appropriate graph #7
tatuchka [14]
Graph K. This is because the cost of a gallon of milk is not increasing constantly, as in a linear rate, but it has only increased a few times in a year. Therefore, graph K shows that a gallon of milk is a steady, unchanged price, then the cost rises and stays the same, then rises again and stays the same. So, it is not a linear graph because the cost of the milk is not going up at a constant rate.
