Question

which slope would be parallel to the line shown in the graph below? a $\frac{5}{2}$ b $-\frac{5}{2}$ c $-\frac{2}{5}$ d $\frac{2}{5}$

Explanation:

Step1: Select two points on the line

Let's take the points (-3, 1) and (2, - 4).

Step2: Calculate the slope using the slope - formula

The slope formula is $m=\frac{y_2 - y_1}{x_2 - x_1}$. Substituting the values: $m=\frac{-4 - 1}{2-(-3)}=\frac{-5}{5}=-1$. Parallel lines have the same slope. Let's calculate the slope of each option:
- Option A: $\frac{5}{2}$
- Option B: $-\frac{5}{2}$
- Option C: $-\frac{2}{5}$
- Option D: $\frac{2}{5}$
We need to recalculate the slope of the given line more accurately. Let's take two clear points on the line, say (-4, 3) and (1, - 2).

Step3: Recalculate the slope

Using the slope formula $m = \frac{y_2 - y_1}{x_2 - x_1}$, we have $m=\frac{-2 - 3}{1-(-4)}=\frac{-5}{5}=-1$. If we consider the general form of slope calculation with two points $(x_1,y_1)$ and $(x_2,y_2)$ on the line. Let's assume two points: $(-2,1)$ and $(3,-4)$. Then $m=\frac{-4 - 1}{3-(-2)}=\frac{-5}{5}=-1$.
We know that parallel lines have equal slopes.
Let's calculate the slope using the points (-3, 1) and (2, -4) again:
$m=\frac{-4 - 1}{2-(-3)}=\frac{-5}{5}=-1$.
We can also use the rise - over - run concept. From one point to another on the line, as we move 5 units to the right (change in x), we move 5 units down (change in y). So the slope of the given line is $\frac{-5}{5}=-1$.
The slope of a line parallel to it will have the same slope.
