Y=-X+4 finding the y intercept, b and slope, mx thus y=mx+b

Find the slope, then use substitute the slope and one of the given points into slope-intercept form.

Slope is change in y over change in x. (7-3)/(-3-1)=-1

Slope-inttercept form is y = mx+b.
3 = -1(1)+b
b=4

y = -x + 4

PLEASE HELP WITH THIS EQUATION!!! WILL GIVE BRAINLIEST AND RATING!!!!!!!
GuDViN [60]

Answer:

-8x+6

Step-by-step explanation:

we know that

The expression Subtract (5x-2) from (-3x+4) is equivalent to the algebraic equation

=(-3x+4)-(5x-2)

=-3x+4-5x+2

Group terms that contain the same variable

Combine like terms

=(-3x-5x)+(4+2)

=(-8x)+(6)

=-8x+6

O GRAPHS AND FUNCTIONSGraphing a function of the form f(x) = ax + b: Integer slopeGraph the function h(x) = -5x +3.
Alborosie
Graphs of linear functions

Since we are graphing a line, if we have two points we can plot the whole line

We evaluate the line in two points in order to locate two places where it passes through. We say y = h(x)

1. If x = 0 then

h(x) = - 5(0) +3

= 0 + 3

= 3

Then y = 3

2. If x = 2 then

h(x) = - 5(2) +3

= -10 + 3

= -7

Then y = -7

Now, we have two points: (0, 3) and (2, -7)

We locate them and then we plot the only straight line that passes through both points

What in math what does it mean when I'd a sample process is in control or not?
Aleks04 [339]
I'm not totally sure what you are asking, but maybe this is a question about dependent and independent variables?

If so, these types of variables are used in math and science as measures. In math, independent variables and dependent variables are the "tools" used in an experiment. 

Independent variables are the variables that are controlled during the experiment. These variables do not change during the experiment.

Dependent variables are the variables whose values change based on the independent variables. These variables are the "outcome" portion. 


I have no idea if this answers your question or not. All I can say is that the "controlled" part of a sample would be the independent variable.
