What is the graph of the function rule?<br><br> y = 3x - 2<br><br> Choose from the pictures

bulgar [2K]

we have

$y=3x-2$

we know that

this is the equation of a line, to identify which is the graph we will proceed to determine the points of intersection with the coordinate axes

1) <u>Find the y-intercept</u>

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

For $x=0$

find the value of y

$y=3*0-2$

$y=-2$

2) <u>Find the x-intercept </u>

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

For $y=0$

find the value of x

$0=3x-2$

$x=(2/3)$

therefore

the answer is the option B ( see the attached figure)

Write the equation of the line perpendicular to 2x+3y=9 that passes through (-2,5). Write your answer in slope-intercept form. S

Harman [31]

ANSWER

$y = \frac{3}{2} x + 8$

EXPLANATION

The line given to us has equation,

$2x + 3y = 9$

We need to write this equation in the slope intercept form to obtain,

$3y = - 2x + 9$

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

The slope of this line is

$m_1 = - \frac{2}{3}$
Let the slope of the perpendicular line be

$m_2$

Then
$m_1 \times m_2 = - 1$

$- \frac{2}{3} m_2= - 1$

This implies that,

$m_2 = - 1 \times - \frac{3}{2}$

$m_2 = \frac{3}{2}$

Let the equation of the perpendicular line be,

$y = mx + b$

We substitute the slope to get,

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

Since this line passes through
$(-2,5)$
it must satisfy its equation.

This means that,

$5= \frac{3}{2} ( - 2)+ b$

$5 = - 3 + b$

$5 + 3 = b$

$b = 8$

Wherefore the slope-intercept form is

$y = \frac{3}{2} x + 8$
