Answer:

$D) y=-\frac{2}{3}x+ 2$

Step-by-step explanation:

$Equation ~ of ~ the ~ line~ is ~ y=mx+b\\\\m= slope\\\\b=y-intercept$

$to ~find ~ the ~ slope~ use ~ formula:-\\\\ slope=\frac{y_{2}-yx_{1} }{x_{2} -x_{1} } \\(0,2)(3,0)$

$slope=\frac{0-2}{3-0}$

$y-intercept ~ is (0,2) ~ so, b=2$

$The ~ equation ~ of ~ the ~ line~ is:- \\$

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

Solve the system of equations below by graphing. x^2-2x+y-3=0 x2+y=0 What is the solution rounded to the nearest hundredth? (–2.

Olin [163]

Answer:

$(-1.5,-2.25)$

Step-by-step explanation:

The first function is $x^2-2x+y-3=0$ .

We make y the subject of this function to obtain,

$y=3+2x-x^2$ .

This is graph will open downwards because $a=-1\:$ .

At y-intercept of this graph, $x=0$ .

$\Rightarrow y=3+2(0)-(0)^2$

$\Rightarrow y=3$

The y-intercept is $(0,3)$ .

At x-intercept $y=0$ .

$0=3+2x-x^2$

$0=(x+1)(x-3)$

$\Rightarrow x=-1,x=3$ .

The x-intercepts are,

$(-1,0),(3,0)$

Also the vertex form of the function is,

$y=-(x-1)^2+4$ .

Therefore the vertex of the parabola is $(1,4)$ .

We plot all the points obtained and draw a smooth curve to obtain the curve as show in the diagram.

The second function is

$x^2+y=0$

$\Rightarrow y=-x^2$

This is the graph of the basic quadratic function $y=x^2$ that has been turned upside down.

This graph also has the vertex,y-intercept and x-intercept all at $(0,0)$ .

We now graph this too on the same graph sheet as the first one to obtain the blue graph as shown in the diagram.

These two graphs intersect at the point, $(-1.5,-2.25)$ .

Therefore the correct answer is B
