Answer:
y = 
Step-by-step explanation:
Let the equation of the line is,
y = mx + b
Here m = slope of the line
b = y-intercept
Slope of a line passing through two points 
and 
is,
m = 
From the graph attached,
Since, the given line passes through (0, -1) and (3, 4),
Slope 'm' = 
m = 
y - intercept 'b' = -1
Therefore, equation of the line will be,
y =
Answer:
There is no x-intercept, only a y-intercept, which would be 1
Circumference of circular path=pi*d^2/4
=44.156
length of light=1.45
light needed=44.156/1.45
=31 approx
Answer:
ill do it when i get home with the explanation attached also !
Step-by-step explanation:
Answer:
Table 4 represents the same linear expression as y = 3 x - 2.
Step-by-step explanation:
Here, the given expression is y = 3 x -2
So now check the any random pair of each table by putting in the given equation.
<u>TABLE 1 : (2,-5)</u>
y = 3x -2 ⇒ -5 = 3(2) -2
or, -5 = -4 , NOT POSSIBLE
<u>TABLE 2 : (0,3)</u>
y = 3x -2 ⇒ 3 = 3(0) -2
or, 3 = -2 , NOT POSSIBLE
<u>TABLE 3 : (1,2)</u>
y = 3x -2 ⇒ 2 = 3(1) -2
or, 2 = 1 , NOT POSSIBLE
<u>TABLE 4 : (1,1)</u>
y = 3x -2 ⇒ 1 = 3(1) -2
or, 1 = 1 , POSSIBLE
checking for (2,4)
4 = 3(2) - 2 ⇒4 = 4 POSSIBLE
Here, table 4 satisfies the given points in the expression y = 3x -2
Hence, it represents the same linear expression .
