Answer:
see graph of y = 5x - 7
Step-by-step explanation:
If graphing is the task, you should rewrite the equation in a y = ax + b form. All straight lines can be described in this form, only the a and b determine which line it is.
Your equation 5x-y=7 has the 5x on the left side, so lets move it to the right. It will get a negative sign (this is the same as subtracting 5x like you did in your picture)
5x - y = 7
-y = 7 - 5x
Now we still have the -y which should be a +y. So we multiply left and right with -1 and get:
y = -7 + 5x
If we swap the -y and 5x (we can, because they are just an addition), we get:
y = 5x - 7
Now the equation is in its "normal" form. It's like the y = ax + b with a and b chosen as a=5 and b=-7.
The normal form is handy because you can immediately see the slope is 5 and the intersection with the y-axis is at y=-7.
Answer:
A line that intersects a circle in exactly one point is called a tangent and the point where the intersection occurs is called the point of tangency.

Answer:
Mattison paid 54 after the discounts for 2 jeans.
Step-by-step explanation:
Original price of the jeans = 35.99
Discount on the jeans = 25%
So, discounted amount on each jeans = 
So, the actual amount paid for 1 jeans = Actual Price - Discounted amount
= 35.99 - 8.99 = 27
So, the price paid for 2 jeans = 27 x 2 = 54
Hence, Mattison paid 54 after the discounts for 2 jeans.
A translation of 2 units up will increase the y coordinate by 2 units and a translation by 5 units to the left will decrease the x coordinate by 5. Hence after these translations point (2,2) becomes
<span>(2 - 5 , 2 + 2) = (-3,4) </span>
When point (-3,4) is reflected in the x axis, its y coordinate changes sign and point (-3 ,4) becomes
<span>(-3,-4)</span>
