Finding the slope (simplest form)

The slope is 3.

Step-by-step explanation:

Slope is equal to rise over run. Let’s take a look at the points given to us on the graph.

To go from the leftmost point to the rightmost point, we rise (go up) 6 units, and then we run over (go right) 2 units. So we have:

Slope = Rise/run = 6/2

Now 6/2 is equal to 3, and that’s the slope.

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.
