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
Greatest to least: 4/9, 44/100, 0.4.
Answer:
Predecessor: 9851
Successor: 9853
Step-by-step explanation:
The predecessor of a number is 1 less than it.
The successor of a number is 1 more than it.

Answer:
y-5=-2/3(x-(-7))
Step-by-step explanation:
I just learned this recently as well so bare with me.
So the point slope form is y-y1=m(x-x1)
So first we have to find the slope. So we do 5-(-1)/-7-1=-6/8=-3/4
So now, we just have to plug in the numbers.
So y-5=-2/3(x-(-7)).
I know that looks a little funky but if you used the slope intercept form, you would get the same answer if you just simplified this version. Of course, you don't have to simplify this version because this version is completely acceptable.
I hope this helped.
