Answer:
3
Step-by-step explanation:
This is a simple rule with negative numbers, a negative divided by a negative is negative. So, 18/6 is 3, so the answer is 3
We know that the perimeter of the smaller parallelogram is 12 cm (2*2 + 4*2). Even though they are similar, this does not make the equation 4*2 + 6*2. Instead, try using the equation for missing side lengths: x/2 = 6/4. To make them similar, the value of x is 3. Plug this into the perimeter formula (3*2 + 6*2) and your answer is 18 cm.

Step-by-step explanation:
Find the diagram to the question attached.
The standard equation of a line in point-slope form is expressed as:
where:
m is the slope of the line
is coordinate point on the line
First is to get the slope of the line.
If after buying 2 lattes, she has $2 left, hence one of the coordinate of the line is (2, 2). We can get the other coordinates from the graph. From the graph, it can be seen that when x = 0, y = 8. Hence the other coordinates is (0, 8)
Hence the slope is -3
Substitute m = -3 and the point (2, 2) into the formula to get the required equation (note that any of the points can be used)
Hence the equation of the line in point-slope form is
