Answer:
y = 15x + 45 *
y - 165 = 15 (x - 8) *
*Both are the same*
Explanation:
1. Find the slope of the line
using the coordinates of x and y - (3/70); (5,100)
take the coordinates to find the slope
5-3 = 2 and 100-70 = 30
rise over run - y over x = 30/2
simplify: 15/1 = 15x
2. Solve for the second equation
use the coordinate (8,165)
Because we only have one point we use point-slope form
y - y*1 = m (x - x*1): *subscript*
plugin using (8,165): y - 165 = 15 (x - 8)
For extra convenience, I added slope-intercept form: y = 15x + 45
Final answer:
y- 165 = 15 (x - 8)
y = 15x + 45
