Answer:
y = -2x + 6
Step-by-step explanation:
y=mx + c
m is the gradient and c is the y intercept
m = (y 2 - y 1) / (x 2 - x 1) = (2-4) / ( 2-1) = -2
y= -2x + c
To find c, just sub one of the coordinates into the eqn:
By using the coordinates (1,4)
4 = -2(1) + c
c = 6
Therefore, the equation is y = -2x + 6
Y= 4x+5 because the slope intercept form would be y=mx+b
mx would be the slope and b is the other thing I forgot what it's called
Answer:
3
Step-by-step explanation:
if the shapes are similar then the measures are proportional:
4/12 = 1/d cross multiply expressions
4d = 12 divide both sides by 4
d = 3
You should by the 8 pound bag because it has more for less.
