<span>y = -1/2x +2 1/2</span>
General equation;
y = mx + c
Calculating the slope;
Change in y/ (change in x) = gradient m
(2-1)/(1-3) = - 1/2
Replacing m gives;
y= -1/2x + c
Calculating the value of c
take point (1,2) above and replace y with 2 and x with 1
2=-1/2 *1 +c
c = 2 1/2
Equation then is
y = -1/2x +2 1/2
Answer: -5
Step-by-step explanation: -3 , -4 , -5 is the third
Answer:
2.5 km
Step-by-step explanation:
15 minutes is
15 minutes * 1 hour/ 60 minutes = 1/4 hour
15 minutes = 1/4 of an hour
10 km/ hour * 1/4 hour = 10/4 km = 2.5 km
One along the X-axis and one along the y- axis
10[(6 + 4) / 2]
10[10/2]
10 * 5
50 <==
