8 0

Answer:

The y intercept is -1

Step-by-step explanation:

the y-intercept is when y = 0

f(0) = -2^2 + 4(0) - 5

f(0) = 4 - 5

f(0) = -1

MatroZZZ [7]

Answer:

(2,4)

Step-by-step explanation:

that would be the answer because when you reflect it over the Y axis you are making the y turn into a + or - depending on what it already is if y=-4 when you reflect it over the y it would be y=4

Find an equation for the line that passes through the points , −4−5 and , 2,5 .
Ronch [10]

Answer:

5x -3y = -5

Step-by-step explanation:

One formula that is useful for writing equations of lines through two points is ...

... (x2 -x1)(y -y1) = (y2 -y1)(x -x1)

Using the given points, this becomes ...

... (2 -(-4))(y -(-5)) = (5 -(-5))(x -(-4))

... 6(y +5) = 10(x +4) . . . . simpify

We can divide by 2 and subtract the left side to get ...

... 0 = 5x +20 -3y -15

... 0 = 5x -3y +5 . . . . . . . this is the <em>general form</em> equation of a line

Subtracting the constant gives the <em>standard form</em> equation.

... 5x -3y = -5

_____

<em>Comment on the solution</em>

As a rule, writing the equation this way from integer coefficients avoids fractions entirely. In the form with x on one side and y on the other, you can choose to move the x-term or leave it be, in order to ensure that it has a positive coefficient in the final equation. (Here we left it alone and moved the y-term.)

The standard form requires that the numbers in the equation be relatively prime (no common factors). That is why we divided by the common factor 2 in the development above.
