To determine the equation of the best fit line, the graphical approach can be done. A line is used in between the given points. Then, the slope and the y-intercept of the line is determined to give us the equation. The equations of two scatter plots are
y = 0.22 x + 0.46
y = 8x + 8.25<span />
Answer:
y=x-2
Step-by-step explanation:
to get -2 to -4 you would have to add -2
if we follow the pattern of subtracting 2 then you would see that -2 is b sense we are subtracting.
The m value doesn't have to change so we would leave the x how it is
The goal for this question is to find the pattern the numbers share though out the table.
Answer:
2x -8
Step-by-step explanation:
f (x) = 3x - 5
g(x) = x + 3,
(f - g)(x) = 3x - 5 - ( x+3)
Distribute the minus sign
= 3x-5 -x-3
Combine like terms
= 2x -8
Answer:
Betty got $180
Step-by-step explanation:
If its 2:3 and 2 is 120, that means 120/2 equals 60. 60*3=180
