△ABC is similar to △DEF .<br><br> AB=5 inches, BC=9 inches, and DE=7.5 inches.<br><br> What is EF ?
Vikki [24]
Similar triangles have corresponding sides with proportional lengths.

AB/BC = DE/EF

5/9 = 7.5/EF

5(EF) = 9 * 7.5

5(EF) = 67.5

EF = 13.5

Answer:

Slope: -\frac{3}{4}

Y intercept: 7

Equation: y=-\frac{3}{4}x+7

Step-by-step explanation:

The slope is found by doing the equation \frac{rise}{run}. When looking at the first two points, it's shown that the rise (difference between the two y values) is -3 (since it decreased by 3) and the run (difference between the two x values) is 4 (since it increased by 4).

This gives us a slope of -\frac{3}{4}.

The y intercept is found by looking at the y value when x = 0. In this picture, it is clear that it is 7.

The equation you want to use is y = mx + b , where b is the y intercept and m is the slope. Just plug in the numbers and you got your equation!

Step-by-step explanation:

\frac{x}{9} > 9 → x > 9 \times 9 → x > 81

* The above answer is written in reverse, which is the exact same result.
