What is slope of the line?

Mathematics

Hello there!

To find the slope of a line, we need to know at least two points contained in the graph of the line.

The slope m of a line passing through the points (x_0,~y_0) and (x_1,~y_1) is given by the formula: m=\dfrac{y_1-y_0}{x_1-x_0}.

As we can see on the graph, two points contained on the line are (-2,~0) and (3,~4).

Using the formula above, we get that:

m=\dfrac{4-0}{3-(-2)}

Subtract the values on both numerator and denominator of the fraction

m=\dfrac{4}{5}~~\checkmark

This is the slope of this line we were looking for.

Find the equation of the line passing through the point (–1, 5) and perpendicular to the line y = – 3x + 4.

Answer:

  A)  3y = x + 16

Step-by-step explanation:

The equation of a perpendicular line can be found by swapping the x- and y-coefficients and negating one of them. The constant will be chosen to match the given point.

Swapping coefficients, we get ...

  -3y = x + c

Negating the y-coefficient gives ...

  3y = x + c

Filling in the given point, we have ...

  3(5) = -1 + c

  16 = c

The equation of the perpendicular line can be written as ...

  3y = x + 16 . . . . matches choice A

_____

Note that choice A is the only equation that gives a line with positive slope. The given equation has negative slope, so its perpendicular must have positive slope.
