Answer:
y= -7x -7
Step-by-step explanation:
All line equations can be represented in the form y = mx + c where a is the gradient or slope and b is the y intercept. (letters used for m and c may vary)
You have been given the slope, = -7 which you can put into y=mx+c
y = -7x + c
The function of a line ^^ means that for any values of x, you multiply it by -7 and add -7. The given coordinates means that when x =0, y = -7. So you can plug these into y = -7x + c , -7 = -7(0) + c . Therefore c = -7
Alternatively, since the value for c is the y intercept, the coordinates immediately give you the answer c. x = 0 which means taht the line intercepts the y axis when y = -7. hence the y intercept = -7

Step-by-step explanation:
Alright, lets get started.
The original photo size is 4 inches wide and 6 inches tall.
So, the ratio of width and height will be = 
The new enlarged photo will be of the same ratio means 2:3
The width of enlarged photo is given as 12 inches.
Suppose new height of enlarged photo is H, so

Cross multiplying

Dividing 2 in both sides
inches
So the height of new enlagred photo will be 18 inches. : Answer
Hope it will help :)

9/2=4.5
27/4.5=6
Given the equation :

We will use estimation to find the value of the given expression
So, the best estimation for the number 576 is = 600
The best estimation for the number 8 is = 10
So, the given expression is approximately = 600 ÷ 10 = 60
===================================================================
We can calculate the error of the approximation as following :
The actual value is : 576 ÷ 8 = 72
So, the difference is = 72 - 60 = 12
so, the percentage of error will be :
