A. slope intercept form is y=mx+b where m is your slope and b is your y-intercept. Since it gives you the slope (4) and the y-intercept (-9) all you have to do is plug it into the equation to get y=4x-9
b. This one is a little bit trickier but by no means impossible. the first thing we want to do is find the slope, and in order to do this we take the second y minus the first and divide it by the difference of the second x and the first x. the way that would look in this case is (10-6)/(4-0) and when we simplify this we get 4/4=1
Since our slope is 1, we just need to find the value of y when x=0, In this problem it is given to us with the point (0,6) if we plug both of this into our equation we get y=x+6 (the 1 in front of the x is optional
Answer:
It would be B,
A. Is a Infinite Decimal number so it wouldn't be that.
B. Seems reliable cause it looks about half of the horizontal line.
C. It wouldnt be 1, the line is way to long.
D. Is a Infinite Decimal number, so it wouldn't be this either.
Answer:
42.9
Step-by-step explanation:
20% of 50 is 10
so its 40
40 + taxes
40 + (40*.0725)
