Answer:
-1.6
Step-by-step explanation:
m=y2-y1/x2-x1
(-4)-4=(-8)
4-(-1)=5
-8/5=(-1.6)
hope this helps :3
if it did pls mark brainliest
Given:
The speed, s, is measured in miles per hour, and distance, y, is measured in yards.
The regression line is given by
...(i)
To find:
The slope and y-intercept of the regression line.
Solution:
The general form of linear regression line is
...(ii)
where x is variable. In the given equation the variable is denoted by s.
On comparing (i) and (ii), we get
It means slope is 52.45 and y-intercept is 4.17.
The slope, b = 52.45, indicates that the distance increases by 52.45 yards for every one mile per hour of speed.
The y-intercept, a = 4.17, is the distance estimated by this model if the speed is zero miles per hour.
Therefore, the correct option is A.
The missing angle would be 68 because the the triangles can be alternate exterior
Answer:
-2 slope so A
Step-by-step explanation:
to find slope it be rise over run
to get from (1,1) to (0,3) you have to rise 2 and go back 1
so numbers form it be 2/-1 what is the same as -2 slope
also you can tell its a negative slope cause everything is descending down.
Sales tax would be 2.50. That makes 500$ 502.50
