consider the line y=2/3x-0 find the equation of the line that is parallel to this line and passes through the point(8, 4).

Mila [183]

To find the equation take the slope 2/3 y-y(1)=m(x-x(1) y-4=2/3(x-8) = 2/3x-16/3 Next solve for y y=2/3x-16/3 +4(turn 4 into a fraction with a common denominator) y=2/3x-16/3 + 12/3 y=2/3x-4/3

Find the equation of the linear function represented by the table below in slope-intercept form.

Degger [83]

Answer:

$y=10x-6$

Step-by-step explanation:

step 1

Find the slope

we have

(0,-6) and (1,4)

The slope is equal to

$m=(4+6)/(1-0)=10$

step 2

Find the equation of the line in slope intercept form

The equation of the line in slope intercept form is

$y=mx+b$

we have

$m=10$

$b=-6$ -----> y-intercept (given value in the table)

substitute

$y=10x-6$

What is the x-intercept of the line with this equation 1/3x+y= -15?<br><br> (_,0)

Sidana [21]

( - 45, 0)

to find the x-intercept let y = 0 in the equation

x = 0 → $\frac{1}{3}$ x = - 15

multiply both sides by 3

x = 3 × - 15 = - 45

x-intercept = ( - 45, 0)

The equation 2 x - 4 y = 7 is written in slope-intercept form. True False

Naily [24]

no it is not an intercept form because the y has to be by itself.

it should be in the form of y=mx+b
