Answer:
2.0
Step-by-step explanation:
x = age
y = average systolic blood pressure
x₁ = 40 years old, y₁ = 110 systolic blood pressure
x₂ = 50 years old, y₂ = 130 systolic blood pressure
∴ Slope of the regression line is 2.0
The absolute value of a number is the distance from point to the origin. Since Paula is located at a position of −12 feet relative to the ground, then the distance from point -12 on the number line to the origin is 12 (distance cannot be negative).
Thus, |-12|=12 and Paula is at a distance of 12 feet.
Answer: correct choice is C
Slope intercept form is y = mx + c.
<em>(where m is the slope, and c is the intercept - hence slope intercept form)</em>
So all you have to do is rearrange the inequality to have y by itself.
-6x + 3y > - 45 <em>(add 6x to both sides)</em>
3y > - 45 + 6x <em>(divide both sides by 3)</em>
y > - 15 + 2x <em>(put the 2x infront of the - 15) </em>
y > 2x - 15

Answer:
y > 2x - 15

The answer is tens because all the numbers the decimal end with an ‘s’, and all the numbers the decimal end with a ‘ths’.
