Answer:
A) 56/x=85/100
C) 56=(0.85)w
Step-by-step explanation:
Sonce 56/.85=65.88, we look for the two that have that answer.
A) 56/x=85/100
cross multiply 5600=85x
divide by 85
x=65.88 - YES
B) p=(0.85)56=47.6 - NO
C) 56=(0.85)w
Divide both sides by 0.85=65.88 - YES
D) x/56=85/100
100x=4760=47.6 - NO

Answer: y=2x-1
We know that the equation of a line is y = mx + b, where m is the gradient and b is the y-intercept.
First to find the gradient, we use the formula y2-y1/x2-x1.
x1 and y1 being the first set of coordinates (2,3) and x2 and y2 being the second set (4,7)
Now we sub in:
m=7-3/4-2
m=4/2
m=2
This is our gradient and we can put it into the equation: y=2x+b
Now we find the y-intercept (b). Since the y-intercept isn’t shown, we can sub in the coordinates to find it.
y=2x+b
Sub (2,3)
3=2(2)+b
3=4+b
-1=b
Sub (4,7)
7=2(4)+b
7=8+b
-1=b
Subbing in both coordinates gives us -1 as the y-intercept, so the finished equation is: y=2x-1
