Answer:
b is -mx+y and m is -b+y/x
Step-by-step explanation:
Answer:
y = 1/2x +2
Step-by-step explanation:
y-y1= m (x-x1)
first find slope
m= 4-1 / 4 - (-2)
m= 3 / 4+2
m= 3/ 6
m = 1/2
you can pick any of the two points to solve for point slope form
y-4 = 1/2 (x-4)
y-4= 1/2x -2
add 4 on both sides
y = 1/2x +2
y-1= 1/2 (x- (-2))
y-1= 1/2 (x+2)
y-1= 1/2x +1
add 1 on both sides
y= 1/2x +2
you should get the same answer with any of the two points you chose
you might want to use a calculator to solve this
if you want to use both points to make sure the answer is correct, you can
if you don't get the same answer with both points then u did something wrong during the equation.
Answer:
b
Step-by-step explanation:
Answer: true
Step-by-step explanation:
Answer: w = 7, x = 6
Step-by-step explanation: Solve by substitution
W + b = 13
rewrite as b = 13 - w and substitute that value for b in the second equation
6.5w + 2b = 57.5 Then solve for w
6.5w + 2(13-w) = 57.5 . Distribute
6.5w + 26 - 2w = 57.5 . Subtract 26 from both sides. Combine like terms and simplify
6.5w - 2w = 57.5 - 26
4.5w = 31.5 Divide both sides by 4.65
w = 7 . Substitute 7 for w in the first equation and solve for b
7 + b = 13 . Subtract 7 from both sides
b = 6
