Answer:
1)86
2)102
3)118
4)134
Step-by-step explanation:
1) so we know that the photographer started off with 86 photographs and has been uploading 16 each month since then
so in month 1 she would have 86
in month 2: 86+16=102
month 3: 102+16=118
month 4: 118+16=134
you could also use the expression
y=16x+70
how to get this equation: get slope(16) by subtracting p coords and m coord
substitute slope in slope intercept form
y=16x+b
insert in a coordinate pair(1,86)
86=16+b
b=70
hence y=16x+70
