Equation 1 ==> y = -4x + 2
Equation 2 ==> y = x - 3 
Substitude equation 2 into 1 
x - 3 = -4x + 2 
-5 = -5x 
x = 1 
Substitude x into equation 2 
y = 1 - 3 
y = -2 
Coordinates is (1, -2)

Answer:
Step-by-step explanation:
<em>Refer to attached</em>
- Height of plants (h) >> Frequency >> Midpoint >> Frequency x midpoint
- 0 <h < 10	>>  1  >> 5 >> 5
- 10 <h < 20 >>	4 >>	15 >>  60
- 20 <h < 30 >>	7 >>	25 >> 175
- 30 <h < 40 >>	2 >>	35 >> 70
- 40 <h < 50 >>	3 >>	45 >> 135
- 50 <h < 60 >> 3 >> 55 >> 165
Sum of frequencies = 20
Sum of frequency x midpoint product = 610
<u>Mean height </u>
