Slope-intercept form: y = mx + b (m is the slope, b is the y-intercept or the y value when x = 0 --> (0, y))
To find the slope(m), you can use the slope formula and plug in 2 points:
(x₁ , y₁) = (0, 2)
(x₂ , y₂) = (4, 5)
[slope is also 
"rise" is the number of units you go up(+ number) or down(negative number). "run" is the number of units you go to the right. If your slope for example is 2, you go up 2 units and to the right 1 unit. If your slope is -2, you go down 2 units and to the right 1 unit.]
^ you could just look at the graph and see how many units a point goes up or down and to the right to get to the next point (goes up 3, to the right 4)
To find b, plug in either of the 2 points into the equaation
(0,2)
2 = b
Answer:
-10
Step-by-step explanation:
1. First, let's simplify both sides of the equation.
2. To find the missing value to make the equation have infinitely many solutions, we need to make both sides of the equation equal.
3. Given that information, means that 4x - 10 has to equal 4x + (-10) because:
4. Now, with the information in #2, let's see if it's true:
-
-
- (0 = 0 means that the equation has infinitely many solutions)
Therefore, the missing number is -10.
So, we're finding ratios first okay, for every 4ft:12in and 6ft:18in so for every one foot there is 3 inches which is your rate of incline 1:3 or every one foot there are 3 inches of incline hope this helped you have an amazing day
Answer:
Step-by-step explanation:
Given formula:
To solve for 
In order to solve for we will try to isolate on one side of the equation.
Steps to isolate .
1) Multiplying both sides by 
to remove fractions.
2) Subtracting both sides by 
3) Subtracting both sides by 
Thus, we successfully isolated on one side. The formula for can be given as:
∴
Answer: -3x²-9x+84
Step-by-step explanation:
Let the zeros be r1 and R2
The equation of a parabola going through those two zeros is
y=a(x−r1)(x−r2)
