Parallel lines have the same slope
Find the slope of points A and B
(y2 - y1)/ (x2-x1)
(5-(-5))/(-1-(-2)) = (5+5)/(-1+2) = 10/1
The slope of the points is 10
In the equation
y = 10x + 12
Y = mx + b, m indicating slope
The slope of the equation is also 10
Because both slope is 10, the line through the points and the equation is parallel
The fraction with the smaller denominator is the greater number.
Answer:
Step-by-step explanation:
Given
Attached graph
Required
The graph equation
Pick any two points, we have:
Calculate slope (m)
The equation is then calculated using:
This gives:
Hence, the equation is:
Well, 2 2/3 is 2 hrs and 40 mins, and he needs that exact amount to have 7 hrs. So, 7hrs-2 2/3hrs = 4 1/3hrs (4 hours and ten minutes.)
Answer:
x= 12 y= -3
Step-by-step explanation:
Rearrange.
x+y=9
x-y=15
Get x by itself, cancel out the y's and you'll get this:
2x=24
x= 12
Plug it in.
12+y=9
Get y.
y= -3
