Answer:

(0.5, 1.3)(0.5, 1.3)

Step-by-step explanation:

Given equations are:

As we can see that the given equations are linear equations which are graphed as straight lines on graph. The solution of two equations is the point of their intersection on the graph.

We can plot the graph of both equations using any online or desktop graphing tool.

We have used "Desmos" online graphing calculator to plot the graph of two lines (Picture Attached)

We can see from the graph that the lines intersect at: (0.517, 1.267)

Rounding off both coordinates of point of intersection to nearest tenth we get

(0.5, 1.3)

Hence,

(0.5, 1.3) is the correct answer

Lines MN and PQ are parallel. Lines RS and TV intersect them. Which statements are true about these lines? Check all that apply.

Maru [420]

The correct answer is: 
RS is perpendicular to MN and PQ.

Explanation: 
We can use the slopes of these lines to determine the answer.
Slope is given by the formula 
m= $\frac{y_{2}- y_{1} }{ x_{2} - x_{1} }$ .

Using the coordinates for M and N, we have: 
m= $\frac{3--1}{3--3} = \frac{4}{6} = \frac{2}{3}$ .

Since PQ is parallel to MN, its slope will be $\frac{2}{3}$ as well, since parallel lines have the same slope.

Using the coordinates for points T and V in the slope formula, we have 
m= $\frac{-4-1}{0--4} =- \frac{5}{4}$ .

This is not parallel to MN or PQ, since the slopes are not the same.
We can also say that it is not perpendicular to these lines; perpendicular lines have slopes that are negative reciprocals (they are opposite signs and are flipped). This is not true of TV either.

Using the coordinates for R and S in the slope formula, we have 
m= $\frac{-2-1}{2-0} =- \frac{3}{2}$ . Comparing this to the slope of RS, it is flipped and the sign is opposite; they are negative reciprocals, so they are perpendicular.
