Answer:

About 8.6

Step-by-step explanation:

d=(x2-x1)^2+(y2-y1)^2

8=x1 8=y1 3=x2 1=y2

(3-8)^2+(1-8)^2

(-5)^2+(-7)^2

25+49

take the square root and you get about 8.6

Answer:

They are, because similarity means that the ratio of the sides are equal and they are proportionate.

Step-by-step explanation:

If you look at the graph, you can count 2 units from the smaller diamond/rhombus to the other diamond/rhombus. If you count the amount of units on each side, you will find that they are not equal, however they should be proportional if you calculate the angles of 90°.

Slope Formula: $m=\frac{y_2-y_1}{x_2-x_1}$

Slope-Intercept Form: y = mx + b

m - slope
b - y-intercept

Step-by-step explanation:

Step 1: Define

y-intercept (0, 5)

Point (1, 2)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m

Substitute [SF]: $m=\frac{2-5}{1-0}$
Subtract: $m=\frac{-3}{1}$
Divide: $m=-3$

Step 3: Write Equation

Plug in variables into the general form.

y = -3x + 5
