Answer:
y=-2/4x + (-4.5)
Step-by-step explanation:
so first we look for the slope which is rise/run.
start with the lower point and count up two.
the count to the left and you have -2/4, thats your slope.
then you chose one point, like (1,-5)
so either using point slope form y-y1=m(x-x1) or standard form y+mx+b
im going to use standard form
plug in your points like so:
y= -2/4x +b
-5= -2/4(1) +b
-5 = -1/2 + b
-5+ 1/2 = b
-4 1/2 =b
so y should equal
y=-2/4x + (-4.5)
im not sure but i hope this helps a bit
Answer:
$4 and $3
Step-by-step explanation:
First, write out the equations as 70x + 29y = 367 and 70x + 45y = 415. Solve by using the elimination method by subtracting 70x from 70x. 45y minus 29y is equal to 16y. 415 minus 367 is 48. Divide 48 by 16, to get y is equal to get y is equal to three. Y represents pepperoni pizzas, so a pepperoni pizza costs $3. Plug a 3 into any equation for y and solve for x. 29 times 3 is 87. 367 minus 87 is 280. 280 divided by 70 is equal to 4, so x is equal to 4.
