Write this in slope intercept form plsss

(–5, 4); slope –3

BRAINLEIST PLZ

Use point slope form y = mx + b, where m = slope & b = y-intercept. We can use point-slope form and the given info to find b.

y = mx + b, m = -3 and (5,4) is a given point (x, y)

4 = -3(5) + b

4 = -15 + b

19 = b

The equation of the line is y = -3x + 19.

Hi,

To solve this, we'll need to use proportional ratios, or ratios that are equivalent.

Since the tree's height is 5 feet long, and has a shadow of x feet in length (x being an unknown value), here's the ratio:
5/x
At the same time, Tyler is 4 feet tall, and has a shadow of 2 feet long, so here's the ratio:
4/2

Because the shadows are proportional to the heights, we'll set the ratios equal to each other:
5/x = 4/2

Now, we'll cross multiply:
5 × 2 = 10:
4 × x = 4x:
4x = 10

Finally, we'll divide both sides by 4:
x = 2.5

The tree's shadow's length is 2.5 feet long. Hope this helped!
