An automobile factory, 1849 parts are made in 4 hours.

<em>1849 / 4 = x</em>

<em />

<u>Step 2:  Solve</u>

1849 / 4 = x

<em>462.25 = x</em>

Point slope equations
Sholpan [36]

Answer:

The point slope equation is: y - y1 = m (x - x1)

m = slope

Step-by-step explanation:

To use this equation, you need to know:

-<u> </u><u>one point on the line</u>

-<u> the slope of the line</u>

<u>First</u>:

(x1,y1) = a known point on the line

m = the slope

(x,y) = any other point on the line

<u>Now</u>:

we plug the numbers into the equation to get y - y1 = m (x - x1)

<u>Then</u>:

you solve the equation

Which graph represents the function f(x) = 2 x – 1 + 2?
tatuchka [14]

Answer:

The graph is positive and would have a y intercept of 1 and a slope of 2 which means choose a point on the graph and add 2 to the y and 1 to the x and you should be at the next point on the line.

Step-by-step explanation:

y=mx+b

f(x)=y

m = slope

b = y intercept

First you need to make it look like y=mx+b

y = 2x - 1 + 2

y = 2x + 1

Now we can say,

m = 2

b = 1

or,

Slope = \frac{2}{1}

y intercept = 1

Slope (m) = \frac{rise}{run}

So the numerator is the value your are going to go up or down along the graph and the denominator is the value of how far you are going to go left or right along the graph. If the slope is positive then the graph is inclining. If the slope is negative, the graph is declining.
