Which shows the equation of the line using function notation?

Mathematics

8 0

In function notation (f(x)=mx+b) m represents the slope and b represents the y-intercept.

In a straight horizontal line the slope is always 0. This cancels out the 'x' factor so you get f(x)=b.

To find b you simply look at where the line crosses the y-axis. in this case it crosses at 2.

When you plug in the y-intercept you get f(x)=2

i need help please! I think I know the answer but for some reason my brain's telling me that it's wrong so if someone could expl
Ivenika [448]

Considering the slopes of the segments, the correct option is:

D. No, because the triangle ABC doesn't have a pair of perpendicular sides.

<h3>When are lines parallel, perpendicular or neither?</h3>

The slope, given by <u>change in y divided by change in x</u>, determines if the lines are parallel, perpendicular, or neither, as follows:

  • If they are equal, the lines are parallel.
  • If their multiplication is of -1, they are perpendicular.
  • Otherwise, they are neither.

Here, we have to find if there are perpendicular segments, that is, if two slopes multiplied have a value of -1, then:

  • mAB = (-7 - 9)/(11 - 1) = -8/5.
  • mAC = (3 - 9)/(-9 - 1) = 3/5.
  • mBC = (3 - (-7))/(-9 - 11) = -1/2.

No sides are perpendicular, hence option D is correct.

These tables represent continuous functions. In which table do the values represent an exponential function.
Dennis_Churaev [7]
If you look at all 4 of these tables. Exponential means a large increase or gradual increase so. With that in mind if you look at table 1, the y column only increases by 5. For B, the y column only increases by 1. For C, the y column increase by 4 then 8 then 16 then 32. Therefore it is exponential. For D it is consistently an increase of 8.

Hope this helps!
