Stella graphs the equation y=13x – 2y=13x – 2 .



Select all statements about Stella's graph that are true.



The graph is a straight line.

The line passes through the origin.

The line passes through the point (0, –2) .

The slope of the line is 3.

The y-intercept of the line is 2.

Respuesta :

y = 13x - 2

the graph is a straight line...TRUE
the line passes thru the origin (0,0)....FALSE
the line passes thru the points (0,-2)...TRUE
the slope of the line is 3...FALSE...the slope is 13
the y int of the line is 2....FALSE...the y int is -2

we have

[tex]y=13x-2[/tex]

Statements

case A) The graph is a straight line.

The statement is True

Because, this is a linear equation of the form [tex]y=mx+b[/tex]

where

m is the slope

b is the y-intercept

In this problem

[tex]m=13\ b=-2[/tex]

case B) The line passes through the origin

The statement is False

Because the point [tex](0,0)[/tex] is not a solution of the linear equation

Verify

Substitute the values of [tex]x=0[/tex] and [tex]y=0[/tex] in the equation

[tex]0=13*0-2[/tex]

[tex]0=-2[/tex] -------> is not true (the point not lie on the line)

case C) The line passes through the point [tex](0,-2)[/tex]

The statement is True

Because the point [tex](0,-2)[/tex] is a solution of the linear equation

Verify

Substitute the values of [tex]x=0[/tex] and [tex]y=-2[/tex] in the equation

[tex]-2=13*0-2[/tex]

[tex]-2=-2[/tex] -------> is  true (the point lie on the line)

case D) The slope of the line is [tex]3[/tex]

The statement is False

Because the slope of the line is [tex]m=13[/tex]

case E) The y-intercept of the line is [tex]2[/tex]

The statement is False

Because

we know that

The y-intercept is the value of y when the value of x is equal to zero

Substitute the value of [tex]x=0[/tex] in the equation and find the value of y

[tex]y=13*0-2[/tex]

[tex]y=-2[/tex]

therefore

the y-intercept of the line is [tex]-2[/tex]

the answer is

The graph is a straight line.

The line passes through the point [tex](0,-2)[/tex]
