Answer:
1. y+5=4x-40
2.y=4x-45
Step-by-step explanation:
To get the slope of a line you do y₂-y₁/x₂-x₁ so we plug in the values -9+5/9-10 and we get -4
Point-slope form states y-y₁=m(x-x₁) where m is the slope so plug in the values we get y+5=4(x-10) and you get y+5=4x-40 then turn this equation into y=mx+b and get y= 4x-45
Answer:
$216435
Step-by-step explanation:
Given : Suppose homes in a big city increase in value 13% every year.
To Find: How much will a home that cost $150,000 be worth 3 years later?
Solution:
Principal = $150000
Rate = 13% =0.13
Time = 3 years
Formula : 
Now substitute the values in the formula


So, The cost of home after 3 years will be $216435
Hence Option B is true
The equation of the line is 
Explanation:
Given that the line passes through the points (-5,-3)
The slope of the line is 
We need to determine the equation of the line.
<u>Equation of the line:</u>
The equation of the line can be determined using the formula,

Let us substitute the points (-5,-3) and the slope
in the above formula.
Thus, we have;

Simplifying, we get;

Subtracting 3 from both sides of the equation, we get;

Hence, the equation of the line in slope - intercept form is 
48 minus 18=30 percent is the increase in the number of apps on Tan's phone
