Answer: y= 1.5x-6
Step-by-step explanation:
1) Find the slope by using change in y over change in x: 
2) Then use the y intercept from the given: -6
3) create an equation in slope intercept form using those factors: y= 1.5x-6
Ed : (0,205)(4,197)
slope(m) = (197 - 205) / (4 - 0) = -8/4 = -2
y = mx + b
slope(m) = -2
(0,205)...x = 0 and y = 205
time to sub
205 = -2(0) + b
205 = b
equation is : y = -2x + 205...so Ed loses 2 lbs per week
Eric :
y = -1.5x + 200...so Eric loses 1.5 lbs per week
when they started, Ed weighed 205 lbs and Eric weighed 200 lbs
* of the two, Eric loses fewer lbs per week. When the two began their respective weight-loss programs, Ed was heavier by 5 lbs.
Have you tried multiplying?
Answer:
The next steps are to:
1) subtract 3.9 from both sides
2) divide both sides by -10.9
3) p = 1.2
Step-by-step explanation:
To solve a multi-step equation, you need to first combine like terms, which was done for your to get the equation: -10.9p + 3.9 = -9.18. At this point, you have a two-step equation where you need to use inverse (opposite) operations to isolate the variable. Whatever you do to one side of the equation, you do to the other:
1) -10.9p + 3.9 - 3.9 = -9.18 - 3.19 or -10.9p = -13.08
2) -10.9p/-10.9 = -13.08/-10.9
3) p = 1.2
