Find an equation for the line perpendicular to y=-1/2x+4 and goes through the point (-1,10)

Artemon [7]

The slope of the perpendicular line will be 2. Remember, a perpendicular slope is the negative reciprocal.

So, we can make the equation $y=2x+b$ . We need to find b, and put b in.

To find b, put in the numbers of y and x.

$10=2(-1)+b$

Solve for b:

$10=-2+b\\b=10+2\\b=12$

Now replace b in the original equation with 12 and that will be the answer:

The answer is $y=2x+12$ .

Y intercept = 1 and parallel to y = 4x - 3

gregori [183]

When a line is parallel to another line, that means both lines have the same slope.

Since the standard form equation for a line is y = mx + b where m is our slope and b is our y-intercept, we know that the new equation will also have m=4.

They give us the y-intercept, b=1

So oue new equation is as follows...

y = 4x + 1
