Y-INTERCEPT: It's called the "y intercept" and it's the y value of the point where the line intersects the y- axis. For this line, the y-intercept is "negative 1." You can find the y-intercept by looking at the graph and seeing which point crosses the y axis. This point will always have an x coordinate of zero.

SLOPE:The slope will be the same for a straight line no matter which two points you pick as you know. All you need to do is to calculate the difference in the y coordinates of the 2 points and divide that by the difference of the x coordinates of the points(rise over run). That will give you the slope.

The Y intercept is where the line crosses the Y axis on a graph. On an equation in the form Y=Mx+B it would be the +B. On an equation the slope is always the Mx

The owner of a new restaurant is ordering tables and chairs. he wants to have only tables for two and tables for 4. the total nu

Papessa [141]

Answer:

4 M + 2 N = 120

Step-by-step explanation:

If we name "M" the number of tables for four people, and "N" the number of tables for two people, then the total number of people to be seated using M tables (of four people) would be the product "4 * M".

Similarly, the total number of people to be seated if the owner has N number of two person tables, would be: "2 * N".

Therefore, if the owner has M four people tables and N two person tables, the total number of people seated at the restaurant would be the addition:

4 * M + 2 * N. Since he wants this number to be 120, we complete the equation making this expression equal to 120:

4 * M + 2 * N = 120

On a cross country vacation, maria filled her 14 gallon gas tank eleven times.wich is the best estimate of how many gallons of g

poizon [28]

The actual answer is 154 but the closest estimate would be 150.
Just multiply the number of gallons filled her gas tank (14) and how many time she filled it (11).

If f(x)= x2/x+3, find f(x+h)?

kompoz [17]

f(x+h) = $\frac{x^{2}+2xh+h^{2} }{x+h+3}$

Step-by-step explanation:

Given,

f(x) = $\frac{x^{2} }{x+3}$

To find the value of f(x+h) we need to replace x by x+h

Hence,

f(x+h) = $\frac{(x+h)^{2} }{x+h+3}$

= $\frac{x^{2}+2xh+h^{2} }{x+h+3}$

[Here, we apply the formula of $(a+b)^{2}= a^{2} +2ab+ b^{2}$ ]

The vertical change between two points is called___. A. up B. down C. run D. rise

morpeh [17]

Answer:

Step-by-step explanation:

The term "rise over run" is frequently used when talking about slope. It means the vertical distance over the horizontal distance, so the answer is D, rise.

6) R E 126 10x + 8 13 + 5x D A) 1 C) 5 B) 7 D) 14

Gemiola [76]

Step-by-step explanation:

step 1. what is the question? maybe the question is what is the value of x in the diagram. okay.

step 2. interior angles of a triangle add up to 180°

step 3. the 3 angles inside the triangle are 10x + 8, 13 + 5x, and (180 - 126)

step 4. (10x + 8) + (13 + 5x) + 54 = 180

step 5. 15x + 21 = 126

step 6. 15x = 105

step 7. x = 7.
