12———-100%
8 ———— x
X=(8*100)/12=800/12=66.66%
Then discount percent is 100-66.66=33.33%
Answer:
y = -2x + 25
Step-by-step explanation:
A standard equation can be in slope-intercept form: y = mx + b
m is the slope, b is the y-intercept.
Plug in the given slope.
y = -2x + b
To find b, plug in the given point (9, 7).
7 = -2(9) + b
Multiply.
7 = -18 + b
Add 18 to both sides to find b.
25 = b
Plug this into your standard equation.
y = -2x + 25
Check by plugging in the given point again.
7 = -2(9) + 25
7 = -18 + 25
7 = 7
Your answer is correct!
Hope this helps!
C, positive linear association. It is positive because it moves upward on the graph (left to right) and it is linear because it is a nearly straight line.
