Which system of linear inequalities is represented by the graph?

y > x – 2 and y < x + 1
y < x – 2 and y > x + 1
y < x – 2 and y > x + 1
y > x – 2 and y < x + 1

Which system of linear inequalities is represented by the graph y gt x 2 and y lt x 1 y lt x 2 and y gt x 1 y lt x 2 and y gt x 1 y gt x 2 and y lt x 1 class=

Respuesta :

hmm, find the lines

they both seem to have a slope of 1
the top one has a y intecept at 1 and the bottom one at -2

y=x+1 and y=x-2
ok, so they both have (0,0) in them

so if ? represents an inequality sign
y ? x+1
0 ? 0+1
0 ? 1
0<1
so y<x+1 is one of the equations

y ? x-2
0 ? 0-2
0 ? -2
0>-2
so y>x-2

y>x-2 and y<x+1

first one

The system of linear inequalities is represented by the graph are [tex]\boxed{y > x - 2}[/tex] and [tex]\boxed{y < x + 1}.[/tex] Option (a) is correct.

Further explanation:

The linear equation with slope m and intercept c is given as follows.

[tex]\boxed{y = mx + c}[/tex]

The formula for slope of line with points [tex]\left( {{x_1},{y_1}} \right)[/tex] and [tex]\left( {{x_2},{y_2}}\right)[/tex] can be expressed as,

[tex]\boxed{m = \frac{{{y_2} - {y_1}}}{{{x_2} - {x_1}}}}[/tex]

Given:

The given options are as follows,

(a). [tex]y > x - 2{\text{ and }}y < x + 1[/tex]

(b). [tex]y < x - 2{\text{ and }}y > x + 1[/tex]

(c).[tex]y < x - 2{\text{ and }}y > x + 1[/tex]

(d). [tex]y > x - 2{\text{ and }}y < x + 1[/tex]

Explanation:

The first line passes the points [tex]\left( {0, 1}\right)[/tex] and [tex]\left( {-1,0}\right).[/tex]

The slope of the line can be obtained as follows.

[tex]\begin{aligned}m&=\frac{{0 - 1}}{{0 - 1}}\\&=\frac{{ - 1}}{{ - 1}}\\ &= 1\\\end{gathered}[/tex]

The slope of the line is [tex]m = 1.[/tex]

The line intersect y-axis at [tex]\left( {1,1}\right)[/tex]. Therefore, y-intercept is 1.

Substitute [tex]\left( {0,0}\right)[/tex] in equation [tex]y< x+1[/tex] to check whether the equation includes origin.

[tex]\begin{aligned}0&<0 + 1\\0&< 1\\\end{aligned}[/tex]

The equation of first line is [tex]y < x + 1.[/tex]

The second line passes the points [tex]\left( {0, -2}\right)[/tex] and [tex]\left({2,0}\right).[/tex]

The slope of the line can be obtained as follows.

[tex]\begin{aligned}m&=\frac{{0 - \left({ - 2} \right)}}{{2 - 0}}\\&=\frac{2}{2}\\&= 1\\\end{aligned}[/tex]

The slope of the line is [tex]m = 1.[/tex]

The line intersect y-axis at [tex]\left( {-2,0} \right).[/tex] Therefore, y-intercept is -2.

Substitute [tex]\left( {0,0}\right)[/tex] in equation [tex]y > x - 2[/tex] to check whether the equation includes origin.

[tex]\begin{aligned}0&> 0- 2\\0&> - 2\\\end{aligned}[/tex]

The equation of second line is [tex]y > x -2.[/tex]

The system of linear inequalities is represented by the graph are [tex]\boxed{y > x - 2}[/tex] and [tex]\boxed{y < x + 1}.[/tex]
