I assume "gradient" means slope, those are the line equations
willow cape
yes
white sorrel
setting x=0 gives you the y-intercepts for both lines
willow cape
ok
willow cape
setting x=0 gives you the y-intercepts for both lines
would you mind explaining it in more simpler terms if you could?
im not used to doing like formulas
white sorrel
picture the xy-plane and a line on it, if the line passes through the y-axis, what value must x have at that point?
willow cape
0
white sorrel
good
willow cape
bc its going through the y axis
white sorrel
whenever a point lies on the y axis, its x coordinate is 0
now what does gradient 3 mean?
whenever I increase x by 1, y changes by how much?
willow cape
whenever I increase x by 1, y changes by how much?
nothing?
sorry if im getting this wrong
white sorrel
that is wrong
you are saying if you press accelerator the car won't be moving faster
do you believe that?
willow cape
no
willow cape
whenever I increase x by 1, y changes by how much?
is it by 1 also??
white sorrel
by 3, because gradient 3
willow cape
oh ok
white sorrel
gradient refers to a ratio
if you move b unit in y direction and a units in x direction, you must always preserve the gradient
so b/a = 3
hence if you increase x by 1, you must increase y by 3
willow cape
oh ok i feel like i understand it now
