The points (20, –2) and (–10, 1) fall on a particular line. What is its equation in slope-intercept form?

Step 1: Determine slope using the points given and the slope formula: y₂ - y₁/x₂ - x₁.

Step 2: Determine b using one of the points listed and pluging it into the slope-intercept formula.

Step 3: Put it together.

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.
