Pythagorean theorem(√82)^2 = 9^2 + x^2

x = 1 cm


15^2 = 9^2 + y^2

y = 12 cm. 

12-1 = 11


Area = 9*11 = 99 cm^2

The points (0,4) and (1, 9) fall on a particular line. What is its equation in slope-intercept
Vitek1552 [10]

Answer:

The equation is y = 5x + 4.

--

Step-by-step explanation:

☆Remember: m =  \frac{y_2 - y_1}{x_2 - x_1}

☆Slope-intercept: y = mx + b

---

☆We need to find the slope first. So just plug in according to the slope formula!

m =  \frac{9 - 4}{1 - 0}  =  \frac{5}{1}  = 5

---

☆Now we need to find the y-intercept. We are going to plug in the slope and a set of coordinates to find the y-intercept.

y = mx + b \\ 9 = 5(1) + b \\ 9 = 5 + b \\  \frac{ - 5 =  - 5 \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: }{4 = b \:  \:  \:  \:  \:  \:  \:  \:  \: }

---

☆Now all we need to do is plug in and we are done!

y = 5x + 4
