Answer:
The slope intercept equation of the line is:
<u> y = (9/8)x - (3/8)</u>
Step-by-step explanation:
- They give us 2 parametric equations to arrive at y = mx + b (Slope intersection equation)
1. X = 8t + 3
2. Y = 9t + 3
- We first convert in terms of t to compare both equations:
1. x = 8t + 3
x - 3 = 8t
t = (x - 3) / 8
- Same for the following:
3. y = 9t + 3
y - 3 = 9t
t = (y - 3) / 9
- Now equating by comparing both equations, we will find y:
(x - 3) / 8 = (y - 3) / 9
9x -27 = 8y -24
9x - 3 = 8y
- Clearing and comparing both parameters gives us:
y = (9/8)x - 3/8
The answer should be b. because 4(4) = 16 and that’s closer to 18.4 than the others.
Slope form: y=mx + b
slope is 2/5, fill into equation
Y = 2/5x + b
Plug in point to find b
1 = 2/5(0) + b
1 = 0 + b, b = 1
The answer is A. Y = 2/5x + 1
