Answer:
y = 2x - 3
Step-by-step explanation:
Step 1: Find the slope. You find the slope by using the formula y2-y1/x2-x1. (2, 1) and (4, 5) are our points. Let's find our values.
y2= 5
y1= 1
x2 = 4
x1 = 2
Plug in the numbers into the equation. 5 - 1 is 4. 4 - 2 is 2. 4/2 is 2. There. Our slope is 2.
Step 2: Find the b value. Keep in mind that an equation in point-slope form is y = mx + b, where m = the slope, and b = the y-intercept. For this part, you will plug in one of the points as x and y to find the b value. let's use point (4, 5)
The equation then becomes 5 = 2(4) + b. As we know, 2 * 4 is 8. Subtract 8 on both sides of the equation to cancel out the right side and isolate the b variable. 5 - 8 is -3. Even if you use the other point for the equation (1 = 2(2) +b), you should get the same answer of -3.

the answer will be 3
To evaluate the functions, set up the table shown below.
x: -10 -5 0 5 10
y=3x+8: -22 -7 8 23 38
y=4x+3: -37 -17 3 23 43
y=x²+6: 106 31 6 31 106
y=3x: -30 -15 0 15 30
y=4x: -40 -20 0 20 40
y=x²: 100 25 0 25 100
The function with the least value is y = 4x.
The function with the greatest value is y = x² + 6.
Answer:
In ascending order, the functions are
4x
4x + 3
3x
3x + 8
x²
x² + 6
You multiply 26 x 50 that equals 1,300
