In slope intercept form, write the equation for each line.
1 answer:
Answer:
A: y = -0.4x -5
B: y = -1x +7
C: y = 1.25x +7
D: y = 3x -5
Step-by-step explanation:
See the attached worksheet. Finding the equations for the graph lines is reasonabvly straightforward, but the number of lines quadruples the space required. We'll find equations of the form y=mx+b, where m is the slope and b is the y-intercept (the value of y when x = 0). The worksheet notes the 4 steps needed:
1. mark any two points on the graph for each line.
2. Find the slope for each line by calculating the Rise/Run
3. Find the y-intercepts from the graph.
4. Assemoble the slopes and intercepts into the four equations.
Use a spreasheet to keep organized, and nbe patient. Check the equations using a free online graphing utility (e.g., DESMOS).

Answer:
Option C
Step-by-step explanation:
Barrel (storage container) is enclosed in a small square fence.
Since, barrel is touching the surfaces from four sides of the cylindrical barrel.
Length of each side of the square fence = Diameter of the barrel
= 2(radius of the barrel)
= 2(1.5)
= 3 feet
Perimeter of a square = 4(Side of a square)
= 4(3)
= 12 feet
Therefore, Option C will be the correct option.
