Answer:
+2 ، +3 ، - 2 ، - 3
Step-by-step explanation:
-12.2÷-6.1=+2
(3(3/7))÷((1(1/7))=+3
16/-8=-2
(-2(2/5))÷(4/5)=-3
Answer:
-4x/7
Step-by-step explanation:
4x + 7y = -35
7y = -4x - 35
y= -4x/7 - 35/7
y= -4x/7 - 5
-4/7 (the slope is the x equation)
Answer:
add 4
Step-by-step explanation:
x^2-4x
Take the coefficient of the x term
-4
Divide it by 2
-4/2 =-2
Square it
(-2)^2 = 4
This is what we add to each side
x^2-4x +4 = 4
First you want to get it into standard form. which would mean you get the x of the side of the y and divide everything by the y's coefficient in this case 3.
3y-x=a
3y=x+a
y=1/3x+a
Now your going to want to turn this into a perpendicular li e which means you flip the coefficient and make it negitive
y=-3x+a
then we fill in the points.
-1=-3(2)+a
Solve
-1=-6+a
-1+6=a
5=a
Now put it in standard form.
y=-3x+5
