What is the equation in point-slope form of the line that passes through the points (7, 5) and (−4, −1)?
Debora [2.8K]

The point-slope form:

y-y_1=m(x-x_1)

m - slope

(x₁, y₁) - point

The formula of a slope:

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

We have the points (7, 5) and (-4, -1). Substitute:

m=\dfrac{-1-5}{-4-7}=\dfrac{-6}{-11}=\dfrac{6}{11}

y-(-1)=\dfrac{6}{11}(x-(-4))\\\\\boxed{y+1=\dfrac{6}{11}(x+4)}

ANSWER ASAP PLEASEEE Part One: Measurements There are many measurements of the human body that are positively correlated. For ex
Artemon [7]

Answer:

You will likely need to actually measure a few people for parts 1 and 2, but  the statement in part 2 should be something like "The length of the forearm of one person will be very similar to the length of their foot" or "As the length of the forearm increases, the length of the foot will increase in similar amounts".

Since the equation in pt.3 is y = 0.860x + 3.302, if x=17, then 0.860(17) + 3.302=17.922

The next question is dependant on pt.1

The data from pt.1 should be somewhat similar to the data you collected, the values between them are different because of the allowed error margin between the two.

The data can be made into a function using the "line of best fit". The equation in part A represents a function because there are no two points where two y coordinates are on the exact same x coordinate.
