Find the slope m.
m = (1 - 2)/(3 - (-1))
m = -1/(3 + 1)
m = -1/4
Use the slope and one of the points and plug into the point-slope formula.
y - 1 = (-1/4)(x - 3)
Isolate y.
y - 1 = (-1/4)x + (3/4)
y = (-1/4)x + (3/4) + 1
y = (-1/4)x + (7/4)
Did you follow?
3/2 since you move 3 spaces horizontally (x) and 2 spaces up (y)
Answer:
340
Step-by-step explanation:
10 ×16=160
12×15=180
160+180=340 so a total of 340 calendars
