Answer correclty

what is the first step to writing an equation in slope-intercept form using the given points: (-1, 0), (-2, -2).

a) use point-slope form

b) substitute -1 for x and 0 for y in y = mx + b

c) find the slope using the slope formula
y2 - y1
x2 - x1

d) find the slope using the slope formula y = mx + b

4. C)

3. B) 9,6 = the number of points you would increase each hour of studying; 65,8 = your score if you studied 0 hours

2. B) The events have a strong positive linear correlation.

1. C) Find the slope using the slope formula:

Step-by-step explanation:

4. (−7, 10) → 10 = 7 + 3 ☑

(−1, 4) → 4 = 1 + 3 ☑

(0, 3) → 3 = 0 + 3 ☑

(3, −2) → −2 ≠ −3 + 3; 0 ☒

3. You obviously have to plug "0" in for x to get your initial value of 65,8, which represents the minimum value of points you would receive if you never were to study, and of course, the 9,6 is the average score increased for every hour studied.

2. The correlation coefficient is 0,02, which is positive, so this would be the obvious choice.

1. You CANNOT write a linear equation without FIRST finding the rate of change [slope]. You will ALWAYS need the rate of change in order to write any linear equation.

Step-by-step explanation:

The first step to find the slope-intercept form is to calculate the slope using its definition

Replacing the given points , we have

So, the slope is 2.

Now, we use the slope-intercept formula

Replacing one point and the slope, we have the slope-intercept form

Which is a line with slope of 2 and y-intercept at 1.

Therefore, the right answer is C, because the first step to find the slope-intercept form, we have to find the slope first.
