Answer:
Y =-10X +5
Step-by-step explanation:
x1 y1 x2 y2
1 -5 0 5
(Y2-Y1) (5)-(-5)= 10 ΔY 10
(X2-X1) (0)-(1)= -1 ΔX -1
slope= -10
B= 5
Y =-10X +5
Answer:
Step-by-step explanation:
They R equivalent because 1 half and two half’s equal A
Length in feet multiplied by width in feet multiplied by height in feet divided by 27 equals cubic yards needed.
When dealing in inches: convert inches to feet by dividing by 12.
For example: pour a 25 ft. sidewalk 5 ft. wide and four inches deep.
(25’ x 5 ‘ x 0.333’) / 27 = 1.54 cubic yards
Note* we achieved 0.333 ft. by taking four inches and dividing by twelve.
Another example: yardage for an 80 ft. driveway, 24 ft. wide and 5 inches deep.
(80’ x 24’ x 0.416’) / 27 = 29.58 cubic yards
The equation of the line is -1/4x=y. If you want to determine what is negative or positive, you look from the left to right. Looking from there, if it is positive, the line would go up, but if it is negative, then it would go down, which it is in this case. Now, to see if it is actually 1/4, try "rise over run." Rise indicates how high you go on the y axis and the run would indicate where you would go on the x axis. Here, the y axis goes up one, and the x axis goes right by 4 (Remember, it is negative)
