12 km/hr, find the speed of Adam's car.

false

step-by-step explanation:

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
