Write an equation of the line passing through the point A(2, 0) that is parallel to the line y = 3x−5 .
sammy [17]
Hello,

In order for lines to be parallel to each other, they need to have the same slope. So, let's plug in the points and slope for point-slope form.

The equation for point-slope form is: y-y1 = m (x-x1)

Let's plug in the points into the equation. 
y-5 = m (x-0), and then let's plug in the slope for "m" : y-5 = 3 (x-0).

After plugging the numbers in, the equation is simplified to y-5 = 3 (x-0). Then distribute the 3 to the parenthesis. y-5 = 3x. To get y by itself, you need to add 5 to both sides. After that, the equation parallel to that equation is: y = 3x + 5.

Hope this helps! =)

For for each quadratic function below use method of completing the Square or averaging the x-intercept to write the equation in
lions [1.4K]

We have the expressions:

f(x)=x^2+6x+15y=x^2-4x+9f(x)=x^2-8xy=x^2+7x-2

Now, with this we operate as follows:

a)

f(x)=x^2+6x+15=x^2+6x+9+15-9\Rightarrow(x+3)^2+6

Then, the axis is x = -3 and the vertex (-3, 6)

b)

y=x^2-4x+9=x^2-4x+4+9-4\Rightarrow(x-2)^2+5

Then, the vertex is (2, 5) and the axis is x = 2.

c)

f(x)=x^2-8x+4-4\Rightarrow(x-2)^2-4

Then, the vertex is (2, -4) andd the axis is x = 2.

d)

y=x^2+7x-2=x^2+7x+\frac{49}{4}-2-\frac{49}{4}\Rightarrow(x+\frac{7}{2})^2-\frac{57}{4}

Then, the vertex is (-7/2, -57/4) and the axis is -7/2.
