What is the graph of the function rule? y = 3x - 2 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) Find the y-intercept

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) Find the x-intercept

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)

Solution set is: ( $7,\frac{13}{3}$ )

Option B is correct

Step-by-step explanation:

We need to find the solution to system of equations

$y=\frac{1}{3}x+2\\y=\frac{4}{3}x-5$

Let:

$y=\frac{1}{3}x+2\,\,\,eq(1)\\y=\frac{4}{3}x-5\,\,\,eq(2)$

Putting value of y from eq(2) into eq(1)

$\frac{4}{3}x-5=\frac{1}{3}x+2\\Combining\,\,like\,\,terms:\\\frac{4}{3}x-\frac{1}{3}x=2+5\\Taking\,\,LCM\\\frac{4x-1x}{3}=7\\\frac{3x}{3}=7\\x=7$

So, value of x=7

Putting value of x into equation 1 to find the value of y:

$y=\frac{1}{3}x+2\\y=\frac{1}{3}(7)+2\\y=\frac{7}{3}+2\\Taking\,\,LCM\\y=\frac{7+2*3}{3}\\y=\frac{7+6}{3}\\y=\frac{13}{3}$

So, value of y = $\frac{13}{3}$

Solution set is: ( $7,\frac{13}{3}$ )

Option B is correct
