A city planner wants to build a road parallel to 2nd Ave . What is the slope of the new road?
ludmilkaskok [199]

Answer:

0

Step-by-step explanation:

By inspection or finding points, we see that 2nd ave is perfectly flat, or in other words, has slope of 0.

If line 1 is parallel to line 2, it means their slopes are the same.

So, the new road parallel to 2nd ave has a slope of \boxed{0}.

Need help please. Thanks so much.
Bingel [31]

Answer:

(-1,\frac{17}{6})

(3,\frac{3}{2})

(-5,\frac{25}{6})

Step-by-step explanation:

The given equation is 2x+6y=15

We substitute the ordered pairs to see which ones satisfies the equation.

For (-1,-8), we put x=-1 and y=-8 to get:

2(-1)+6(-8)=^?15

-2+-48=^?15\\-50=^?15

This is not true.

For (-1,\frac{17}{6})) we put x=-1 and y=\frac{17}{6} to get

2(-1)+6*\frac{17}{6})=15\\ -2+17=15\\15=15

This is true

For (3,3/2) we have 2(3)+6(3/2)=15

This implies 6+9=15

15=15

This is also True

For (-5,25/6), we have 2(-5)+6(25/6)=-10+25=15

This is also true.
