Because they have the same inclination so if we try to draw them on a diagram they will be parallel to each other.

The solutions to an equation are the coordinates of the points that belong to both lines.
The points where the graphs meet belongs to both lines and are solutions to the system of equations.
In our case the lines have the same slope therefore are parallel, so they will never meet so they will have to points that are common to both lines in the same time, so the system of equations given has no solutions.

Answer:

A: f(x)\leq -2

Step-by-step explanation:

After graphing the equation, the highest point is (-1,-2). Since f(x) is the 2nd number in the coordinates (x, f(x)), the range is f(x)\leq -2

Graph a line with a slope of -5 that contains the point -3,-4
guapka [62]

Answer:

The equation of the line is 5x + y + 19 = 0

Step-by-step explanation:

The equation of the line with slope 'm' and given a point (x₁, y₁) passing through it we use the Slope - one - point form which is given by:

                                    y - y₁ = m(x - x₁)

The point given is: (-3, -4) and the slope is -5.

We get the equation of the line to be:

y - (-4) = -5(x - (-3))

⇒ y + 4 = -5(x + 3)

⇒ y + 4 = -5x - 15

⇒ 5x + y + 19 = 0. is the required equation of the line.
