A. The
y-intercept (b) of a linear equation is obtained when x = 0. Therefore from the
given table,
y - intercept
= 8
Since at
time zero the displacement is 8 ft, this means that the horse was already
outside the barn initially.
B. The
average rate of change of the function represents the slope of the linear
equation (m). This can be calculated using the formula:
average rate
of change = m = (y2 – y1) / (x2 – x1)
m = (158 –
58) / (3 – 1)
m = 50
<span>C. Since we have determine the y-intercept and
the slope, we can formulate the linear equation:</span>
y = m x + b
y = 50 x + 8
The domain
is the value of x. When y = 508, x is equivalent to
508 = 50 x +
8
<span>x = 10 hrs</span>
Answer:
Where is the picture for the question?
Answer:
12
Step-by-step explanation:
plug in -7 where x is
5 - (-7) = 12
Answer:
Step-by-step explanation:
(1) A typical form of equation of a line is:
with, is slope and is y-intercept.
(2) Another straight line has equation in form of:
with is slope and is y-intercept
(3) If these two lines are perpendicular, according to the property of two perpendicular lines on the two-dimensional plane, we have:
x = -1
(4) Transform the given equation of original line into typical form:
<=>
<=>
<=>
=>
=>
=> Option D: is correct (Slope = )
