the top right graph is the graph of the given equation
The equation of a line in ' slope- intercept form ' is
y = mx + c → (mis the slope and c the y-intercept
y = x - 2 is in this form
Note if m is positive the line slopes upwards from left to right and if m is negative the line slopes downwards from left to right
here m = so line must slope upwards from left to right
That restricts the choice to the 2 graphs on the right
here c = -2 , that is the y-intercept is - 2
Which is the graph on the top right

Answer:
$500
Step-by-step explanation:
We can find the original price of the camera through a proportion. A proportion is an equation where two ratios or fractions are equal. The ratios or fractions compare like quantities.
<u>Second Discount</u>
20% off means we paid 80%. We know we paid $328 of some price.
I can now cross-multiply by multiplying numerator and denominator from each ratio.
I now solve for y by dividing by 80.
The price after the first discount was $410.
<u>First Discount</u>
We will repeat the steps above with $410. 18% off means we paid 82%.
I can now cross-multiply by multiplying numerator and denominator from each ratio.
I now solve for y by dividing by 82.
The original price was $500.
