7 because if you do the inverse operation: 7 x 9 = 63
Answer:
1
Step-by-step explanation:
y=mx+b, equation for slope-intercept line
we can work out the equation based on given two points (1,1) and (7,4)
- m=(y2-y1)/(x2-x1)= (4-1)/(7-1)= 3/6= 1/2
y=1/2x+b
For (1,1)
For (7,4)
So we get
The answer is 1 for question mark
