Answer:
m (slope) = 37
Step-by-step explanation:
use the slope-line formula, y2 - y1/x2 - x1
put in coordinates (5, 20) for x1 and y1
put in coordinates (4, -17) for x2 and y2
simplify
Answer: 7
Step-by-step explanation: 7 is the y intercept in the slope intercept form. y=slopex+y-intercept
Answer:
A. 7
Step-by-step explanation:
