For this case we have that by definition, the slope of the line is given by:
According to the statement we have:
Substituting the values:
Thus, the value of 
Answer:
Answer:
<3 and <7 Corresponding Angles
<2 and <7 Alternate Exterior Angles
<4 and <5 Alternate Interior Angles
<3 and <6 Alternate Interior Angles
Slope-intercept form:
y = mx + b "m" is the slope, "b" is the y-intercept
For lines to be perpendicular, their slopes have to be the opposite/negative reciprocal (flipped sign and number)
For example:
slope is 2
perpendicular line's slope is -1/2
slope is -3/4
perpendicular line's slope is 4/3
#1: The slopes are the same, meaning they are parallel lines
#2: First isolate the "y" in the first equation
-4x + 5y = -5
5y = -5 + 4x
y = -1 + 4/5x They are not perpendicular because the slopes are 4/5 and -4/5
#3: Isolate "y" in the second equation
8y = 3x - 32
y = 3/8x - 4 They are perpendicular
#4: Isolate "y" is the 1st equation
10y = -9x
y = -9/10x They are parallel lines
The 3rd choice is your answer
Answer:
down below
Step-by-step explanation:
The line slopes downwards as we move from left to right. The vertical intercept is 5. The gradient measures the steepness of the line. A large positive value of m means the graph increases steeply as you move from the left to the right. Answer.
Answer:
4.7 cm
Step-by-step explanation:
= 7 so side length of the square is 7
7 x 4 = 28 so perimeter is 28cm
28 - 9.3 - 9.3 = 9.4
9.4 / 2 = 4.7 cm
