17.7 is the answer just divide by the whole number
1st-24 blocks 2nd-A and C 3rd-38 4th-B 5th-C
The answer is -1,1 ------ y is -1 and x is 1 because when you substitute for x , which is 4y+5 in the equation 2x-3y=5, you get y as -1. They all you have to do is use y in the equation and figure out what x is as well while solving...:):)
Answer:
5
Step-by-step explanation:
Original line: y=1/2x-9
Perpendicular lines have opposite slopes from the original lines. Since the original slope is 1/2, the perpendicular slope will be -2/1 or -2. The numbers switch places and switches from positive to negative.
New line: y=-2x+b
To solve for the y-intercept (b), plug the given coordinates (3,2) into the x and y spots in the equation:
2=-2(3)+b
Now, solve for b.
2=-6+b
Add 6 to both sides.
8=b
The y intercept is 8.
Now, your perpendicular line equation is:
y=-2x+8
I hope this helps :)
