Answer:
Perpendicular lines have slopes that are opposite and reciprocal. Therefore, the line we are looking for has a -3 slope.
y= -3x+b
Now, we can substitute in the point given to find the intercept.
2= -3(4)+b
2= -12+b
b=14
Finally, put in everything we've found to finish the equation.
y= -3x+14
3.70+1.25+1.48= 6.43.
20-6.43=13.57
You would get $13.57
Answer:
For the given functions, the value of g(5)-f(5) = 17
Step-by-step explanation:
Here, the given functions are:
f(x) = -3x + 17
So, f(5) = -3(5) + 17
= -15 + 17 = 2
And 
So, f(5) = 2 and g(5) = 19
⇒g(5) - f(5) = 19 - 2 = 17
Hence, for the given functions, the value of g(5)-f(5) = 17
Answer:
Okay so I am not positive but I will try to help you out. Okay so the line of best fit would positive. Because it is all going up. The approximate slope is 3/4 Because slope is change in y over change in x. The y intercept of the line of best fit would be (0,0). This is because when drawing the line you can see that it would intercept the y-axis at zero. My steps taken were basically just looking at it and peicing everything together. If you want to get more involved with slope you could pick to coordinates which I will include and do change in y over change in x.
My points I will pick are (1,1) and (5,2)
2-1/5-1=3/4
therefore approximate slope is 3/4
Like I said I am not positive but I am just trying to help out in some way.
