What is the equation of the line described below written in slope-intercept form the line passing through the point (-1,5) and p

gregori [183]

The correct answer is y=-x+4

Further explanation:

Given equation of line is:

$x+y = 10$

Comparing it with the standard point-slope form

$y = mx+b$

We get

y = -x+10

m = -1

As the new line is parallel to given line it will also have m=-1 as slope of two parallel lines is equal

For finding b, we will put the point and value of m in standard form

$y = mx+b\\5 = (-1)(-1) + b\\5 = 1+b\\5-1 = b\\b=4$

Hence the equation will be:

$y = (-1)x+4\\y = -x+4$

The correct answer is y=-x+4

Given y=(2x+3)2, choose the standard form of the given quadratic equation

katrin2010 [14]

$y=(2x+3)^2 = 4x^2 +12x +9$

Taking 4 out from first two terms, we will get

$y=4(x^2+3x)+9$

Now we divide the coefficient of x by 2 and add and subtract the square of the result, we will get

$y=4(x^2+3x+\frac{9}{4}-\frac{9}{4})+9$

Distributing 4

$y=4(x+\frac{3}{2})^2+9-9$

Cancelling 9

$y=4(x+\frac{3}{2})^2$

And that's the required standard form.
