Answer:
The parallel line has slope
The perpendicular line has slope
Step-by-step explanation:
Equation of a line:
The equation of a line has the following format:
In which m is the slope.
Parallel lines:
Parallel lines have the same slope.
Perpendicular lines:
If two lines are perpendicular, the multiplication of their slopes is -1.
In this question:
We have the following line:
Placing it in the general format
So this line has slope
Parallel line:
Same slope, so the parallel line has slope
Perpendicular line:
Multiplication of the slopes is -1. So
The perpendicular line has slope
Answer:
40%
Step-by-step explanation:
i used a calculator
The answer in centimetres is 250cm
Let y and x be the numbers that varies directly (that means they keep the same proportion)
Then we have 7y = 3x, OR y/x =7/3 (this ratio should be kept for any value of x and y:
y/x = 7/3, if y = 28, then 28/x = 7/3 or x = (3)(28)/7 = 12
SO X = 12
Answer:
Step-by-step explanation:
First, find the slope. The slope can be found by using the following equation:
slope
Let:
Plug in the corresponding numbers to the corresponding variables:
Plug in into the equation for slope:
y = mx + b
Note that:
y = y
m = slope
x = x
b = y-intercept
Plug in a point into the equation. In this case, I will use b(3 , 0). Remember (x , y):
Equation:
