Angle 2 is 143
angle 4 is 37
angle 7 is 143
angle 8 is 37
The y intercept is -4 and the 2/3x is the slope
You want to find the time <em>t</em> such that

Divide both sides by $200 :

Take the logarithm of both sides:

Divide both sides by 0.04 and solve for <em>t</em> :

Hi there.
We want to find out how many times we are going to multiple 15 to get 1,575. When we know this, we can just multiple the product by 1 to get the number of teachers.
1,575 ÷ 15 = 105
Cool. So now we know that 15 goes into 1,575 that amount of times.
Let's multiply by 1.
105 · 1 = 105
The ratio of students to teachers is 1,575:105
We can check our work by dividing both numbers by the GCF.

Answer:
2
Step-by-step explanation:
To find the slope given two points you do 
so we just plug in the y values and x values




Therefore the slope is 2
