The equation of line l1 is y= 5x +1 the equation of l2 is 2y-10x+3 =0 show that these two lines are parallel

see explanation

Step-by-step explanation:

Parallel lines have equal slopes

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y-intercept )

y = 5x + 1 is in this form with slope m = 5

rearrange 2y - 10x + 3 = 0 into this form

add 10x to both sides

2y + 3 = 0 + 10x ( subtract 3 from both sides )

2y = 10x - 3 ( divide all terms by 2 )

y = 5x - ← in slope- intercept form with slope m = 5

Since both lines have a slope of 5 then they are parallel lines

In order to find slope, it is easiest to put the equation in slope-intercept form, or y=mx + b, where m = slope and b=y-intercept.  In L1, y=5x +1 indicates a slope of 5.  In L2, the equation is not in slope-intercept form, so we must solve for 'y' using inverse operations:  2y - 10x +3 = 0, start by subtracting 3 from both sides of the equal sign:  2y - 10x +3 -3 = 0 - 3 gives us 2y - 10x = -3.  Then add '10x' to both sides:  2y - 10x + 10x = -3 + 10x gives us 2y = 10x - 3.  Lastly, divide all terms by 2:  2y/2 = (10/2)x - 3/2 or y = 5x - 1.5.  Now that L2 is in slope-intercept form, we can see that m=5 as in L1, so since they have the same slope, they are parallel lines.  

EXPLANATION

hope this helps

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
