halp me plzzzzzzzz
what do you have so far? were you able to get started?
am struggling to do the graph with an equation...aawwnnn
Let's break it down piece by piece. let's make x = time in minutes and y = distance from home Also, we'll assume she starts at home so that means y = 0 when x = 0. She starts at the point (0,0) The first part says that ` She rides on a flat road at a constant rate of 0.4km/minute for 5 minutes` so what that part means is the line will go through (0,0) and have a slope of 0.4. This line will span from x = 0 to x = 5 to represent the fact that she is traveling this speed for 5 minutes

OK

OK PAPA
The 2 comes from the fact that 5*0.4 = 2
` She then rides up a hill at a rate of 0.3km/minute for 3 minutes.` what would this look like?
SO basically they have given us the slope and x value, we can find the y value...or distance ok
yes if she traveled 0.4 km/min for 5 min, then she traveled 5*0.4 = 2 km x = 5 y = 2 giving the point (5,2)
