Write an equation of the line in slope-intercept from?

Step-by-step explanation:

This is for the first question.

Slope-intercept is:

m - slope

b - y-intercept

We are given the slope of and a y-intercept of 2.

Plug in the values:

The geometric mean has to multiply to 100. There’s a 4. To get to 100, you need a 25. AB+DB should equal 100. So x would have to equal 21. To prove this, 25 x 4 = 100. The square root of 100 is 10 which proves the answer for x is 21. I hope this helps!
