Answer:
3.5 (meters per second)
Step-by-step explanation:
To calculate the slope, we need two points. Let's see if we can select two points from the graph.
From the graph, we can pick out two possible points.
At the beginning, (0,2.5) is a valid candidate.
And at the end, with (5,20). Thus, let's use the slope formula to calculate the slope.
The slope formula is:
Let (0,2.5) be x₁ and y₁ and let (5,20) be x₂ and y₂. Thus:
Simplify:
Thus, the slope is 3.5 meters per second.
Further notes:
And the entire equation will be:
Answer:
a) y=3x-11
b) y=-1/3x-1
Step-by-step explanation:
First find the slope of the line
rise/run
rise is 3
run is 1
so slope is 3
since this line is parallel to "a", the slope of "a" will also be 3
the equation of a will be
y-y1=3(x-x1) -- where x1 and y1 will be the points it passes through (3,-2)
y-(-2)=3(x-3)
y+2=3x-9
y=3x-9-2
y=3x-11
since this line is perpendicular to "b", the slope of "b" will also be reciprocal negative , -1/3
y-y1=-1/3(x-x1) -- where x1 and y1 will be the points it passes through (3,-2)
y-(-2)=-1/3(x-3)
y+2=-1/3x+1
y=-1/3x+1-2
y=-1/3x-1
You probably just need to simplify the expression. To do this you just combine like terms. So you would subtract 38 from the 10 to get -28x and then subtract 47 from 36 which gives you -11. Your expression should be -28x-11.<span />
