Plz help I'll mark brainliest.

Fill in the blanks:
For any line graphed on a coordinate plane, similar ___ prove that the slope of the line is the ___ same between any pair of points that lie on the line.

Choices for blank space 1:

circles
right triangles
squares

Choices for blank space 2:

Never
Sometimes
Always

right triangles

always

Step-by-step explanation:

Similar triangles are obtained by rise/run

Since the ratio for all triangles are the same, they have the same slope.

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
