What is the slope of the segment shown for a staircase wnth 10-inch treads and 7.75-inch risers? As you walk up (or down)
the stairs, your vertical distance from the floor is a linear function
of your horizontal distance from the point on the floor where you
started. Is the function discrete or continuous? Explain.

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1

f(x)=2/3x+4/3 is the answer because is whose power in the senate is equal to the power of the speaker of the house?

step-by-step explanation:

system of linear equation

step-by-step explanation:

as given in the data

a= 20 , b= -12

let us suppose that it is a straight line equation

now we know the formula for the system of linear equation

b= ma + c )

here m is slope of a straight line which is equal to formula

m=   (ii)

and here c is a constant

now putting the value of a and b in equation (ii)

m=

m=

putting the value of a,b and m in equation (i) gives us

-12 = + c

-12=-12 + c

adding 12 to both sides

-12 +12 = -12 +12 +c

0 =c

or c=0

as the value of the constant is zero which gives us that it is a linear equation and this order pair satisfies the system of linear equations.
