Step-by-step explanation:
Let the equation of the perpendicular line is,
y = mx + b
where m = slope of the line
b = y-intercept
From the graph, slope of the line passing through (0, -1) and (3, 1),
m' = 
m' = 
m' = 
To get the slope (m) of this line we will use the property of perpendicular lines,
m × m' = (-1)
m × = -1
m = 
Equation of the perpendicular line will be,
x-intercept of the line is (-3) therefore, point on the line is (-3, 0)
0 = 
b = 
Equation of the line will be,
Step-by-step explanation:
a general line equation is
y = ax + b
the original line is
y = 3/5 x + 10
the factor of x is always the slope (inclination of the line).
it is "y change/x change".
the slope of a perpendicular line (angle of 90°) is turning the slope of the original line upside-down and flips the sign.
so, it is -5/3.
we use the point information to get the right "b" for our new line :
-5 = -5/3 × 15 + b
-5 = -5×5 + b
-5 = -25 + b
b = 20
so, the perpendicular line equation going through (15, -5) is
y = -5/3 x + 20
Answer
42
Explanation
Let’s say:
Set of envelopes: {a,b,c,d,e,f,g}
Set of postage stamps: {1,2,3,4,5,6}
For an envelope you can have:
1a 2a 3a 4a 5a 6a (6 different combinations)
This applies to all 7 different types of envelopes.
Therefore 7 • 6 = 42
The is 0.666666666666666666667 so i dont know which way you want to swing because if you round up it is 0.7 and 0.6 doesn't repeat infintely so your choice
