Well, there's a lot of ways you could do this. Because it's multiple choice, you can just pick a pair of points and whatever equation it works in, that's your answer. In this case, it's the third one down.
If you didn't have multiple choice you would use these two formulas:
m = (y2 - y1)/(x2-x1)
y - y1 = m (x - x1)
Answer:
The equation in point-slope form is 
.
Step-by-step explanation:
We are given the slope and a coordinate pair of a line.
- Slope: 2
- Coordinate Pair (x, y): (4, 6)
Therefore, we can now label our coordinate pair and substitute our values into the formula. Our formula is:
We can label our coordinate pairs with the 
labeling method.
Therefore, since our two coordinates are:
We can label 4 as x₁ and 6 as y₁.
Then, we are able to determine <em>m</em>, or our slope.
Now, let's set up our equation.
Therefore, our line is y = 2x - 2. However, the problem asks for it in point-slope form. So, this is exactly what we have in Step 2: y - 6 = 2(x - 4).
Answer:
10.9 people per square mile
Step-by-step explanation:
If you look at the chart, there are 41.5 people per square mile in Colorado and 52.4 people per square mile in Iowa. To find the answer, simply subtract:
52.4 - 41.5 = 10.9
Given:
BD is parallel to XY.
One of the angle is 85°
To find:
The value of y.
Solution:
Parallel lines BD and XY cut by a transversal line.
Angle y and 85° are alternate interior angles.
Alternate interior angle theorem:
If two parallel lines are cut by a transversal line, then the pairs of alternate interior angles are congruent.
⇒ y = 85°
The value of y is 85.
D = distance from finish line
D= 5 - 1/3x
Distance from the finish line is equal to the distance of the start line from the finish line, minus one third of a km times the number of minutes hes been running.
using given variables; D= 5 - 1/3*3
D=5-3/3
D=5-1
D=4
