The point (a,b) would be in quadrant 2 (the one on the top left)
y-intercept is the Y value when x is 0
Y = 60
so this means if a person studies 0 hours they will get a 60 on the test
So B would be the answe
I’m pretty sure it’s 16 sorry if I counted wrong.
Answer:
D
Step-by-step explanation:
See in title it says thousands,
so multiply whatever number in graph by 1000
Rhode Islands shows 45 in graph, so:
45x1000=45,000
Let she work for x hours as carpenter !
so earned money = 20x
and for blacksmith she must work for 30-x hours
so earned money = (30-x) ×25
so putting in eqn;
20x+25(30-x) = 690
so, x= 60/5 = 12
so she works for carpenter for 12 hrs and 30-12= 18 hrs for blacksmith !!.....answer !!
