Answer:
y = - x - 1
Step-by-step explanation:
Assuming you require the equation of the line
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - , then
y = - x + c ← is the partial equation
To find c substitute (12, - 4) into the partial equation
- 4 = - 3 + c ⇒ c = - 4 + 3 = - 1
y = - x - 1 ← equation of line
Answer:
Step-by-step explanation:
slope-intercept form: y = mx + b
Given:
Slope(m) =
Point = (-1, 3)
To write the equation in slope-intercept form we need to know the slope(m) and the y-intercept(b). Since we already know the value of m, we can use it and the given point to find b:
Now that we know the values of b and m, we can write the equation:
Answer:
Option D. 8 units
Step-by-step explanation:
step 1
Find the area of rectangle
The area of rectangle is
step 2
Find the length side of the square with the same area of rectangle
The area of a square is
where
b is the length side of the square
we have
substitute
take the square root both sides
therefore
The length side of the square is 8 units
Both trains travel for 7 time units.
Train A travels 385 distance units, so its speed is
Train B travels 577.5 distance units, so its speed is
Note that the units are not specified, but considering that we're talking about trains, the graph is likely to be showing distance in km (or miles) and time in hours.
Also, the distance traveled by train B is not perfectly aligned with the grid, so I assumed that it was the average between the two ticks of 550 and 605.
