Y=5/2x -4 how to graph it
Igoryamba

Looking at y=-%285%2F2%29x we can see that the equation is in slope-intercept form y=mx%2Bb where the slope is m=-5%2F2 and the y-intercept is b=0 note: y=-%285%2F2%29x really looks like y=-%285%2F2%29x%2B0

Since b=0 this tells us that the y-intercept is .Remember the y-intercept is the point where the graph intersects with the y-axis

So we have one point  

Now since the slope is comprised of the "rise" over the "run" this means

slope=rise%2Frun

Also, because the slope is -5%2F2, this means:

rise%2Frun=-5%2F2

which shows us that the rise is -5 and the run is 2. This means that to go from point to point, we can go down 5 and over 2

So starting at , go down 5 units

and to the right 2 units to get to the next point  

Now draw a line through these points to graph y=-%285%2F2%29x

So this is the graph of y=-%285%2F2%29x through the points  

Hope this helps

Solve for variable. 3p/5 + 8/5 =1
nordsb [41]

\\ \sf\longmapsto \dfrac{3p}{5}+\dfrac{8}{5}=1

\\ \sf\longmapsto \dfrac{3p+8}{5}=1

\\ \sf\longmapsto 3p+8=5

\\ \sf\longmapsto 3p=5-8

\\ \sf\longmapsto 3p=-3

\\ \sf\longmapsto p=\dfrac{-3}{3}

\\ \sf\longmapsto p=-1

Using it's concept, the range of the function is given by:

y ≥ 1

<h3>What is the range of a function?</h3>


The range of a function is composed by the set that contains all output values for the function. Considering the graph of the function, the range is given by all the values of y, which compose the vertical axis of the graph.

Looking at this graph, the function assumes values of 1 and greater, hence the range of the function is given by:

y ≥ 1.
