A line passes through the point (1,4) and is perpendicular to the line with equations y=-1/5x+2. what's the equation of the line

jekas [21]

To find the slope of the perpendicular line, you can take the negative reciprocal of the slope of the line it is perpendicular to.

Taking the negative reciprocal of -1/5 gives 5.

Now we have y=5x+b, where b is the y-intercept. Since we know that the perpendicular line passes through the point (1,4), we can substitute those values into the equation we have to find b.

y=5x+b

4=5(1)+b

4=5+b

b=-1

Therefore, the equation of the perpendicular line is y=5x-1.

X = y - 3<br> 2x + y = 12<br> pls hurry i need badly

$\huge \colorbox{yellow}{Question}$

$2x + y = 12$

$\huge \colorbox{yellow}{Answer}$

$x = y - 3 \: (equation \: 1)$

$2x + y = 12 \: (equation \: 2)$

Substituting the value of x in

( equation 2)

$2x + y = 12$

$2(y - 3) + y = 12$

$2y - 6 + y = 12$

$2y + y = 12 + 6$

$3y = 18$

$y = 18 \div 3$

$y = 6$

Now we get y = 6

Substituting the value of y in

( equation 1 )

$x = y - 3$

$x = 6 - 3$

$x = 3$

Now we get x = 3
