Answer:
y=-9/2x-10
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(-1-8)/(-2-(-4))
m=-9/(-2+4)
m=-9/2
y-y1=m(x-x1)
y-8=-9/2(x-(-4))
y-8=-9/2(x+4)
y=-9/2x-36/2+8
y=-9/2x-18+8
y=-9/2x-10
Answer:
x-coordinate = 0
Step-by-step explanation:
In a coordinate plan there are two perpendicular lines one is x-axis and another is y-axis
x-axis is a horizontal line and y-axis is a vertical line.
Both lines intersect each other at (0,0).
On x-axis, y-coordinate remains same , i.e., y=0.
On y-axis, x-coordinate remains same , i.e., x=0.
Therefore, the x co-ordinate of any point lying on the y axis is 0.
Pre tax in first city = x
pre tax in 2nd city = x - 500
0.09x + 0.095(x - 500) = 970
0.09x + 0.095x - 47.5 = 970
0.09x + 0.095x = 970 + 47.5
0.185x = 1017.50
x = 1017.50/0.185
x = 5500 <== first city
5500 - 500 = 5000 <== 2nd city
