Answer:

In the equation of a straight line (when the equation is written as "y = mx + b"), the slope is the number "m" that is multiplied on the x, and "b" is the y-intercept (that is, the point where the line crosses the vertical y-axis). This useful form of the line equation is sensibly named the "slope-intercept form"

Is Statistics mathematics or science? Defend your answer.

siniylev [52]

Statistics is related to maths because we study, use and even consider statistic problems with reference to mathematics.

• It is mostly used to find the census, which is maths.

• It is used to find interest rates and other banking terms using statistics, which is again related to math.

• It is also used to find the average people living in a village or panchayat, which is also math.

Therefore I strongly believe that Statistics is Maths.

Thank You!

Slope-Intercept Form: y = mx + b

m - slope
b - y-intercept

Slope Formula: $\displaystyle m = \frac{y_2 - y_1}{x_2 - x_1}$

Step-by-step explanation:

Step 1: Define

Identify variables.

y-intercept (0, 45)

Point (5, 30)

Step 2: Find Slope m

Simply plug in the 2 coordinates into the slope formula to find slope m.

Substitute in points [Slope Formula]: $\displaystyle m = \frac{30 - 45}{5 - 0}$
[Order of Operations] Simplify: $\displaystyle m = -3$

Step 3: Find Equation

Our variables are h (x-axis) and temperature in °F (y-axis). Our slope tells us that for every increase in hours h, the temperature decreases by 3 °F. Our y-intercept tells us what temperature °F it was in the beginning (45 °F).

Substitute in variables [Slope-Intercept Form]: t = -3h + 45

And we have our final answer!
