Problem 1
It appears the line is going through the points (-1,-4) and (0,5)
Let's find the slope
The slope is 9
The y intercept is b = 5 as this is where the graph crosses the y axis.
We go from y = mx+b to y = 9x+5
<h3>Answer: y = 9x+5</h3>=======================================================
Problem 2
This line goes through the points (0,4) and (5,5)
We'll follow the same exact steps as before
First we need the slope
The y intercept is the y coordinate of (0,4) so it's b = 4
<h3>Answer:Answer: 346.4
Step-by-step explanation:
The whole triangle ABD is a 30-60-90 right triangle. In 30-60-90 triangles, the smallest side is x, the middle side is x, and the largest side/hypotenuse is 2x.
Side AB is the smallest side and therefore x=300. Side BD is the middle side and so we can use x and we get BD=300
=519.615
The question is asking for CD, and we know that CD can be equal to BD minus BC since that would isolate CD
Triangle ABC is also a 30-60-90 triangle but the 300 feet is the middle side in this triangle. So we can do 300=x and divide 300 by radical 3 and get that x=173.205
Side BC is the smallest side of this triangle so it would be x and x is 173.205.
Now that we have the whole side BD and the part of it BC. We can subtract BD by BC (519.615-173.205) and we get that CD=346.4
