Check the picture below.
so let's use those two points the line passes through to get its slope.
Answer:
Step-by-step explanation:
Exponential growth function can be represented as follows
y =
Here y increases exponentially with respect to t . As t increases , rate at which y increases is increases .or
dy / dt =by , or rate of increase depends upon y itself
dy / y = bdt
integrating on both sides
lny = bt
y =
It represents very fast increase in y .
The unrestricted growth of population of human being is an example of exponential growth . As population increases , rate of growth of population also increases.
For exponential decay function
y =
The decay of a radioactive material is an example of exponential decay function.
Answer:
The slope-intercept form equation of the line perpendicular to y = x + 10 and passes through point (-2, 7) is y = 2x + 11 ⇒ Not in the choices
Step-by-step explanation:
The slope-intercept form of the linear equation is y = m x + b, where
- m is the slope
- b is the y-intercept
The product of the slopes of the perpendicular lines is -1, if the slope of one is m, then the slope of the other is
- To find the slope of the perpendicular line to a given line reciprocal the slope of the given line and change its sign
∵ The equation of the given line is y = x + 10
→ Compare it with the form of the equation above
∴ m =
→ Reciprocal it and change its sign to get the slope of the ⊥ line
∴ m⊥ = 2
→ Substitute in the form of the equation above
∴ y = 2x + b
→ To find b substitute x and y in the equation by the coordinates of
a point on the line
∵ The line passes through the point (-2, 7)
∴ x = -2 and y = 7
∵ 7 = 2(-2) + b
∴ 7 = -4 + b
→ Add 4 to both sides to find b
∵ 7 + 4 = -4 + 4 + b
∴ 11 = b
→ Substitute it in the equation
∴ y = 2x + 11
The slope-intercept form equation of the line perpendicular to y = x + 10 and passes through point (-2, 7) is y = 2x + 11
<u><em>Note:</em></u> The answer is not in the choices
