Answer:

$y-4=\frac{1}{5}(x-7)$

Step-by-step explanation:

The point-slope form of a line is given by:

$y-y_1=m(x-x_1)$

Where

(x_1,y_1) is the coordinate pair (any of the points given)

m is the slope. The ratio of change in y coordinates by x coordinates

Let's calculate the slope:

$m=\frac{4-3}{7-2}\\m=\frac{1}{5}$

Now, it is given "y - 4", so y_1 is 4, so they are using the coordinate pair (7,4). So we can say x_1 = 7

Now we have all the values, lets write the equation:

$y-y_1=m(x-x_1)\\y-4=\frac{1}{5}(x-7)$

This is the point-slope form.

a polygon has an area of 225 square meters. A similar polygon is created with an area that is triple the first. By what factor i

GuDViN [60]

The area of the original polygon is:
A = 225 m ^ 2
The similar polygon area is:
A '= (k ^ 2) * (A)
Substituting values:
3 * 225 = (k ^ 2) * (225)
Clearing k we have:
k ^ 2 = 3
k = (3) ^ (1/3)
Answer:
The length of each side increased by:
k = (3) ^ (1/3)

Bruce bought a map that cost $7.35 he used a $10 bill to pay for his map what is the change

ankoles [38]

$2.65

You can get this by subtracting the 7.35 from the 10.

10 - 7.35 = 2.65
