Midge baked 6 cookies and 4 brownies. Midge only has enough ingredients to bake at most 25 cookies or brownies total. Let x represent the number of more cookies and y represent the number of more brownies that Midge can bake. Which of the following graphs best represents the relationship between x and y?
@phi @mathslover
this one is a bit confusing, isn't it? they say Let x represent the number of *more* cookies and y be the number of *more* brownies. they also say she already baked 6+4 = 10 "baked goods" she can only bake up to 25 "baked goods" total. Because she already baked 10, she can only bake 25-10, or 15 *more* of either type.
in other words, x+y= 15 can you write this equation in slope-intercept form ( that is an easy way to figure out which graph to choose)
no, sorry I can't :( I'm still confused
@phi ?
in that case, test a few numbers. when x is 0, what is y using x+y= 15 ?
y = 15 when x = 0
@phi
yes, that means the point (0,15) is on the line so you should find all the choices where (0,15) is on the line. those might be the answer. find another (easy) point. if y is 0 what is x? use x+y=15
although, looking at your choices, only one of the graphs has the line go through (0,15)
so it's the first answer?
yes
thanks :)
yea thanks
