-11.3 is rational or irrational ? explain? 0.083 and 2.1371938 to please if its not much to ask?
zloy xaker [14]
Ignore the - sign for now.   11.3   =   11.3        113
                                                         -------  = ----------
                                                             1             10

Since this is the ratio of two integers, 11.3 is rational.  So is 11.3.

                                                                             83
If you really mean   <span>0.083, this is rational:  it is ---------
                                                                            1000

If y ou meant </span><span>0.083333333 ... , that's also rational:  1/12 is equivalent.</span>

what is the slope and equation of a line that is perpendicular to the y-axis passing through (-5,-3)?​
Illusion [34]

Answer:

Slope is m=0

y=-3

Step-by-step explanation:

The slope of any line that is perpendicular to the y-axis is zero.

The reason is that any line that is perpendicular to the y-axis is also parallel to the x-axis and the slope of the x-axis is zero.

The equation of any line perpendicular to the y-axis is and passes through (a,b) is y=b.

The given point is (-5,-3) hence the required equation is

y=-3

What is the slope-intercept equation for the line below? (0,2) (5,4)
Alla [95]
Find the slope first
m = (y₂ - y₁)/(x₂ - x₁)
m = (4-2)/(5-0)
m = 2/5

Find the slope-intercept equation
y - y₁ = m(x - x₁)
y - 2 = 2/5 (x - 0)
y - 2 = (2/5)x
y = (2/5)x + 2
