The slope of the line below is -1. write the point-slope equation of the line using the coordinates of the labeled point.​
omeli [17]

Answer:

y+9=-1(x-4)

Step-by-step explanation:

Point Slope Form is:

y-y_1=m(x-x_1)

When:

'm' is the slope.

(x_1,y_1) is the coordinate.

We are given the slope of -1 and the coordinate of (4,-9).

So:

m=-1\\x_1=4\\y_1=-9

Using the information and replacing the values we get:

y+9=-1(x-4)

So, the line equation in point slope form should be: y+9=-1(x-4)

Which equation could generate the curve in the graph below?y=3x^2-2x+1
4vir4ik [10]
If you are asking what is the graph of y = 3x^2 -2x+1.

Then, the attached file would be the answer.

To check, b^2 - 4(a)(c), for each equation and use these facts:

If b^2 - 4(a)(c) = 0, there is only one real root meaning, the graph touches the x-axis only in one point.

If b^2 - 4ac > 0, there are two real roots meaning, the graph touches the x-axis in two different points.

If b2 - 4ac < 0, there are no real roots then the graph does not touch the x-axis. This would be the case for y = 3x^2 - 2x + 1.
Solution:
(-2)^2 -4(3)(1) = 4 - 12 = -8 < 0 will result in not real roots.
