The correct answer is D, y = 7x + 5
Calculate the slope by doing y2 - y1 / x2 - x1
y2 - y1 / x2 - x1
61 -33 / 8 - 4
28 / 4
7
Next find the y intercept by looking at the graph, which is 5 in the case
Put it together and you have y = 7x + 5, or option D
The answer is 3x-12y because you combine the like terms so 2x+x=3x and -8y-4y=-12y
10in would be the appropriate scale factor for the drawing. 2000 is 10x200. If each inch represents 200 feet, then you would need 10 to reach the desired scale factor of the original building
Answer:
I'm not sure if your asking for an entire equation but the points for the vertex would be (-3,-4)
JY would be 14 because of simple subtraction
