Answer:
450 Area
Step-by-step explanation:
50 blocks long and 9 blocks wide. If you do 50x9 you get the area inside of the park.
Answer:
d. slope; intercept
Step-by-step explanation:
A regression equation is represented in the form :
y = mx + c (linear regression)
Where y = predicted variable
m = slope of regression line
x = independent variable
c = intercept (where the regression line crosses the y axis).
For a multiple regression equation where there are more than one independent, then we have multiple slopes
y = c + m1x1 + m2x2 +...mnxn
Hence, the slope. And intercept are the two key part of a regression equation which enables us to make prediction and correlation about the dependent and independent variables.
The slope will be the same, so we know the equation will be y=-2x+b. But there is a different b.
For x=4, y will be 1 because the point (4,1) is given.
So 1=-2*4 + b => b = 9
So the equation of our parallel line is y=-2x+9
If we subtract 1 from both sides, we get y-1 = -2x + 8
Then factor out -2 on the right hand side: y-1 = -2(x - 4)
That's answer A!
