Answer:
Step-by-step explanation:
Find the slope by doing rise/run
-2/3
Find the y intercept: (0, -2)
The equation will be y = -
x - 2
The total value would be the amount he put in plus the amount he earns in interest. The answer should be 424
Answer:
Slope - intercept form 
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given points are ( -9 ,-8 ) and (-6,6)
slope of given two points

The equation of the straight line passing through the points and having slope


3 y + 2 4 = 14 x + 126
3 y = 14 x + 126 - 24
3 y = 14 x + 102


Slope - intercept form y= mx +C
Slope - intercept form 
Answer: The mechanic worked for 4.25 hours for the fourth customer.
First find out the slope.
Y^2-y^1/x^2-x^1
210-90/3-1=60
Slope: 60
Then find out what the y-intercept is by plugging in values we know into y=mx+b
90=60(1)+b
30=b
Y=60x+30
Substitute the y with 285 to find out the x (hours)
285=60x+30
4.25=x
