Answer:
The equation of line is
.
Step-by-step explanation:
If a line passes through two points and
, then the slope of the line is
From the given graph it is clear that the line is passes through the points (0,1) and (4,4).
The
The slope intercept form of a line is
where, m is slope and b is y-intercept
The slope of the line is and y-intercept is 1, so the equation of line is
Therefore, the equation of line is
.
Answer:
Step-by-step explanation:
To answer all the parts given find the equation of the line given in the graph.
Let the equation is,
y = mx + b
m = slope of the line
b = y-intercept
x = time
y = Amount of water
Slope of a line passing through two points and
is,
m =
Slope of the given line passing through (0, 80) and (1, 320)
m =
m = 240
Y-intercept 'b' = 80
Therefore, y = 240x + 80 will be the equation.
a). At x = 0
y = 240(0) + 80
y = 80 liters
b). As the time is increasing amount of the water is increasing
Rate of increase in the water = Slope of the line
= 240 liters per minute
