Answer:
.
Step-by-step explanation:
From the given table it is clear that x and y are linearly related.
Now, any two points that satisfy the relation between x and y are sufficient to express the equation.
The first two given points are (2,3), and (4,4).
Therefore, the equation is

⇒ . (Answer)
Answer:
b
Step-by-step explanation:
172/387 = 4/t
Let t = time to travel 387 miles
172t = 4(387)
172t = 1548
t = 1548/172
t = 9
Answer: 9 hours
Answer:
-0.4
Step-by-step explanation:
Answer:
is the equation of line in slope intercept form.
Step-by-step explanation:
Line runs through points begin ordered pair negative 3 comma 0 end ordered pair and begin ordered pair 0 comma 4.
First ordered pair: (-3,0)
Second ordered pair: (0,4)
We have two points and need to find equation of line in slope intercept form
y-intercept, when x=0 , (0,4)
Equation of line in slope intercept form:
y=mx+b
where, and b=4
Required equation:
Thus, is the equation of line in slope intercept form.
