Answer: The equation is y= -2x -4
Step-by-step explanation:
The slope intercept form is like y=mx+b so we know the slope which is m but we just need to find the y intercept.
and we will use the given coordinates to find the y intercept by putting in the x and y coordinates into the formula y=mx + b
-6= -2(1) + b
-6= -2 + b
+2 +2
b= -4
0.19 for one cookie and 0.59 for one doughnut
x for how much one cookie costs and y for how much one doughnut costs
6x+4y=3.5
12x+5y=5.23
solve by substitution: (elimination would work too)
4y=3.5-6x
y=0.875-1.5x
12x+5(0.875-1.5x)=5.23
12x+4.375x-7.5x=5.23
4.5x=0.855
x=0.19
now use x to solve for y:
6(0.19)+4y=3.5
1.14+4y=3.5
2.36=4y
y=0.59
Check the work: 6(0.19)+4(0.59)=3.5
Answer: Linear
Step-by-step explanation: A linear function can have different rates of change over different intervals.
(I don't know if this is correct, but this is my understanding of it.)

Answer:
Given:
f(x) = 2x² + 3
g(x) = x² - 7
To Find:
(f - g)(x)
Step-by-step explanation:
(f -g)(x) = f(x) - g(x)
= (2x² + 3) - (x² - 7)
= 2x² + 3 - x² + 7
= 2x² - x² + 3 + 7
= x² + 3 + 7
= x² + 10
