How do u solve for y
sergey [27]
If you are talking about y as in y = mx + b then i can help you.
Let’s use this example:
3x + 4y + 2 = 16
What you first need to do is get y alone on one side of the equation. The way we do this is by subtracting 2 from both sides. That gives us 3x + 4y = 14
After this let’s move the x over to the other side into point slope form. 4y = -3x + 14
Now just divide everything by 4.
The answer is y = -3/4x + 7/2

write the equation of the line that passes through the point (-1,-6) and is perpendicular to a line that passes through the poin
Burka [1]

Answer:

y=\frac{2}{3}x-\frac{16}{3}

Step-by-step explanation:

step 1

Find the slope of the given line

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

we have

(-2,5) and (-4,8)

substitute the values in the formula

m=\frac{8-5}{-4+2}

m=\frac{3}{-2}

m=-\frac{3}{2}

step 2

Find the slope of the perpendicular line to the given line

we know that

If two lines are perpendicular, then their slopes are opposite reciprocal (the product of their slopes is equal to -1)

so

m_1*m_2=-1

m_1=-\frac{3}{2} ----> slope of the given line

therefore

m_2=\frac{2}{3} ---> slope of the perpendicular line to the given line

step 2

Find the equation of the line in point slope form

y-y1=m(x-x1)

we have

m=\frac{2}{3}

point\ (-1,-6)

substitute

y+6=\frac{2}{3}(x+1)

step 3

Convert to slope intercept form

y=mx+b

isolate the variable y

y+6=\frac{2}{3}x+\frac{2}{3}

y=\frac{2}{3}x+\frac{2}{3}-6

y=\frac{2}{3}x-\frac{16}{3}
