Ezra needs at least $37 to buy some books. She already has $25. Which graph best represents all the possible dollar amounts that Ezra can save to buy the books? Number line graph with open circle on 0 and 12 and shading in between. Number line graph with closed circles on 0 and 12 and shading in between. Number line graph with open circle on 12 and shading to the right. Number line graph with closed circle on 12 and shading to the right.

Number line graph with closed circle on 12 and shading to the right.

Explanation:

if you see Ezra needs $37 and if she has less than $12 then she will not have $37. she needs exactly $12 or more. The closed circle tells us that 12 is a answer and the shading to the right means more than 12.

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
