Answer:
y-intercept is -18
Step-by-step explanation:
The total y=mx+b equation is y=4x-18, you can check in a calculator. I checked on a graphing calculator, and solved it via graphing on a piece of paper.
A line is drawn on the coordinate plane that passes through the point (3,-6) and has a slope of 4. The y-intercept of the line is -18.
What is a slope?In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction.
Given:
A line that passes through the point (x, y), with a y-intercept of b and a slope of m, can be represented by the equation,
y = mx + b.
If a line passes through two points (x₁ ,y₁) and (x₂, y₂) ,
then the equation of line is
y - y₁ = (y₂- y₁) / (x₂ - x₁) x (x - x₁)
To find the slope;
m = (y₂- y₁) / (x₂ - x₁)
m = 4 (given)
So, the equation of the line is,
y - y₁ = m(x - x₁) equation 1
And here
x₁ = 3 and y₁ = -6.
Substituting the values to the equation 1,
y - (-6) = 4 (x - 3)
y+6 = 4x -12
y = 4x -18.
Comparing with the slope-intercept form,
we get y-intercept b = -18
Therefore, the equation is y = 4x -18 and y -intercept of the equation is -18

Step-by-step explanation:
D = b² - 4ac
#1D = 10² - 4 · 3 · 2
D = 100 - 24
D = 76
#2D = (-5)² - 4 · 1 · (-4)
D = 25 - (-16)
D = 26 + 16
D = 42
#3D = 7² - 4 · 1 · (-8)
D = 49 - (-32)
D = 49 + 32
D = 81
#4D = 0² - 4 · 1 · (-9)
D = 0 - (-36)
D = 36
#5D = (-6)² - 4 · 5 · 10
D = 36 - 200
D = - 164

An elevator travels down from the top floor of a skyscraper. The graph below represents its height, in feet, over time in seconds. What does the slope of the line represent?
Answer:
So Y, which represents height, goes down depending on how far you are in time, which is X.
The slope of the graph represents the elevator's descent speed, calculated as 12 feet per second based on the points (1, 838) and (2, 826).
The Slope of the line in the graph represents the rate of change of height with respect to time, or the speed of the elevator's descent.
In this case, the slope can be calculated using the formula: slope = (change in height) / (change in time). We know that the elevator's height changes from 838 feet at 1 second to 826 feet at 2 seconds,
So, the change in height is : 838 - 826 = 12 feet, and the change in time is 2 - 1 = 1 second.
Therefore, the slope is 12 feet/second, this indicates that the elevator is descending at a speed of 12 feet per second.
