Find the rule to the table

dexar [7]

to get the equation of any straight line we simply need two points off of it, hmm let's use those one in the picture below from the table.

$(\stackrel{x_1}{2}~,~\stackrel{y_1}{8})\qquad (\stackrel{x_2}{12}~,~\stackrel{y_2}{-2}) ~\hfill \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{-2}-\stackrel{y1}{8}}}{\underset{run} {\underset{x_2}{12}-\underset{x_1}{2}}}\implies \cfrac{-10}{10}\implies -1 \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{8}=\stackrel{m}{-1}(x-\stackrel{x_1}{2}) \\\\\\ y-8=-x+2\implies \boxed{y=-x+10}$

Consider the linear system of equations y=2/5x-1 and 2x-3y+1=0 graph the system of equations

nlexa [21]

We can see that the lines intersect at: (-5,-3)

Step-by-step explanation:

Given system of equations is:

$y = \frac{2}{5}x-1\ \ \ \ Eqn1\\2x-3y+1 = 0\ \ \ \ Eqn2$

Lets convert the second equation in the same form as the first equation

$2x-3y+1 = 0$

Adding 3y on both sides

$2x-3y+1+3y = 0+3y\\2x+1 = 3y\\3y= 2x+1$

Dividing both sides by 3

$\frac{3y}{3} = \frac{2x+1}{3}\\y = \frac{2}{3}x+\frac{1}{3}\\$

The graph of equation can be plotted using manual graphing or any online graphing calculator

We will use the Desmos online graphing calculator to graph the equations (Picture attached)

We can see that the lines intersect at: (-5,-3)
