Answer:
y = -2x + 9
Step-by-step explanation:
y = -2x + 7
(4, 1)

y = -2x + 9
Answer:
The weekly sales must be $12,600
Step-by-step explanation:
if their pay is the same, the equations have to be equal
amelia = jayden
185 +.095x = 311 +.085x
subtract .085x from each side
185 +.095x-.085x = 311 +.085x-.085x
185+.01x = 311
subtract 185 from each side
185-185+.01x = 311-185
.01x = 126
divide by .01
.01x/.01 = 126/.01
x = 12600
Answer:
Positive correlation.
Step-by-step explanation:
This is a positive correlation. Because the dots don't jump around too much, they are steadily moving in one direction, so they have correlation.
But also, the dots are moving upwards, in a positive direction. So, that's why they have a positive correlation.
