I believe it is asking you to state if there’s any correlation between science and math test scores based on the graph.
Hope this helps!
Answer:
The coefficient of variable term y is -1
Step-by-step explanation:
We have an expression given in the question that is:
6 - y + 3
We have to find the coefficient of the variable term.
In mathematics, variable can be defined as any term which is to be measured. For example in the given expression, y is the variable because its value is unknown yet and it has to be measured.
Coefficients are the number the multiply the variable
For example
In 2x, x is the variable and 2 is the coefficient.
Now in the given expression, we have
6 - y + 3
or
6 + (-1)(y) + 3
So considering (-1)(y), the variable is y while its coefficent is -1

Step-by-step explanation:
The distance, D, is given by the speed, S, times the time, T:
D = S*T
<u> D </u> <u> S*T </u> <u> Time </u> <u>Equation for each segment</u>
200 = 150T1 T1 = 1.33 hr y=150x 0 T 1.33 hr
300 = 200T2 T2 = 1.5 hr y=200x 1.33 T 2.83 hr
400 = 250T3 T3 = 1.6 hr y=400x 2.83 T 4.43 hr
The graph can be drawn as three lines, ione each for the three segments, each having the slope shown in the equation for that segment and extending between the range of values for T (which is the "x" in the equation and on the graph). The y axis will be ditance, in km.
The overall speed is the total distance divided by the total time:
D(km) T(hr)
1) 200 1.33
2) 300 2.83-1.33 = 1.5
3) <u>400</u> <u>4.43-2.83 = 1.6</u>
900 km 4.43 hr
(900 km)/(4.43 hr)
Average speed = 203.01 km/hr
