Find the slope and y-intercept of the line.
y = 2x + 5

Answers

y = 2x + 5 is in the form of y = mx + b, where m is the slope and b is the y-intercept.

y = 2x + 5
y = mx + b

m = slope = 2
y-intercept = b = 5

The slope of the line is 2.
The y-intercept of the line is 5.

The slope and y-intercept of the line are 2 and 5 respectively.

How to find the slope and y-intercept of the line?

The equation of a line is an algebraic form of representing the set of points, which together form a line in a coordinate system.

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

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

We have:

y = 2x + 5

Comparing with y = mx + b:

slope (m) = 2

y-intercept (b) = 6

It is found that there is a relationship between the weight of an airplane and the maximum speed it can travel. The results were published claiming that a lighter airplane can travel faster. What is the problem with reporting the result this way?

Answers

Answer:

Missing data or correlation and causality

Step-by-step explanation:

The results of a hypothesis should always be very accurate and display the research data that allowed us to reach the presented result. The lack of data, correlation and causality do not give the search result credibility because it does not show the factors and variables that show that the result is correct. This is the problem of the result stated in the question. The result is that lighter aircraft can travel faster, but it does not say the data, nor the variables and situations that led to this conclusion.

planes could not go if the airplane is to heavy or slow so that is why they both matter

jenny went to mall with $120 in her wallet. spent $25.65 on a shirt $4.58 on a snack . how much money does she left

Answers

She started off with 120 then spent 25.65 on a shirt then 4.58 on a snack
25.65 and 4.58 are the numbers that you have to add together then subtract from 120.
so 25.65+4.58=30.28
So then you subtract 30.28 from 120 and get 89.72
She has $89.72 left over
Hope I helped :)

$89.77, you subtract both items from her total and that is what she has left in her wallet
