5^2 +12^2= diagonal^2
25+144=d^2
169= d^2
D= 13
Y=mx+b
plug in the point
3=-1*-4+b
3=4+b
b=-1
y=-1x-1
Answer:
The lines are certainly not parallel!
Step-by-step explanation:
The slope of line J is 3/2, while the slope of line k is exactly 1 :)
Answer:
3x−4y=9 −3x+2y=9
Add these equations to eliminate x: −2y=18
Then solve−2y=18
for y: −2y=18 −2y −2 = 18 −2 (Divide both sides by -2)
y=−9
Now that we've found y let's plug it back in to solve for x.
Write down an original equation: 3x−4y=9
Substitute−9for y in 3x−4y=9: 3x−(4)(−9)=9
3x+36=9(Simplify both sides of the equation)
3x+36+−36=9+−36(Add -36 to both sides)
3x=−27 3x 3 = −27 3 (Divide both sides by 3) x=−9
Answer: x=−9 and y=−9
Hope This Helps!!!
