Answer:
The slope is 10 (y =10x +15)
Step-by-step explanation:
When using two coordinates to find the slope of a linear function, I choose (-2,-5) and (2,35) *but you can choose any two.
The formula for finding the slope is y-y divided by x-x.
so... (35)-(-5)=40 NOTE: I did 35 minus -5 but you can also do -5 minus 35.
2-(-2)=4 But just remember to do it the same order for
subtracting the x coordinates.
40/4=10
The cost of 4 walnuts is 4/12*33=11
the cost of 8 pounds of chocolate is 8/12*33=22
the cost of 1 pound of walnuts is 11/4= $2.75 and the cost of one pound of 1 pound of chocolate chips is 22/8=$2.75
A) No solutions
B) It's because the question gives you that both lines have the same slope. Remember that having the same slope makes the two lines parallel, which means they'll never intersect.
66 is 3x 22 so multiply the sales tax at 22$ by 3 or 1.87 * 3
