eduard

Answer:

c)   6x - 5y = 15

Step-by-step explanation:

Slope-intercept form of a linear equation:  y=mx+b

(where m is the slope and b is the y-intercept)

Maria's line:  y=-\dfrac{5}{6}x+8

Therefore, the slope of Maria's line is -\frac{5}{6}

If two lines are perpendicular to each other, the product of their slopes will be -1.

Therefore, the slope of Nate's line (m) is:

\begin{aligned}\implies m \times -\dfrac{5}{6} &=-1\\m & =\dfrac{6}{5}\end{aligned}

Therefore, the linear equation of Nate's line is:

y=\dfrac{6}{5}x+b\quad\textsf{(where b is some constant)}

Rearranging this to standard form:

\implies y=\dfrac{6}{5}x+b

\implies 5y=6x+5b

\implies 6x-5y=-5b

Therefore, <u>option c</u> could be an equation for Nate's line.

Step-by-step explanation:

It's mostly an assumption based on the pattern of number placement, so I apologize in advance if this is incorrect.

I'm not sure what this is for.

likoan [24]

In order to construct a scatter plot, the essential items include;

A: The variable measured on the vertical axis. This is because the variables on both axes is the major reason why the graph is being constructed, so the variable must be identified.

B: The variable measured on the horizontal axis, for the same reason as stated above.

D: The scale of vertical and horizontal axes. This helps to read off the range of the data set without going beyond the limit
