The point P(5,1) lies on the curve y=5x. If Q is the point (x,5x), find the slope of the secant line PQ for the following values
sveta [45]

Answer:

5

Step-by-step explanation:

We have been given that the point P(1,5) lies on the curve y=5x. Q is the point (x,5x). We are asked to find the slope of the secant line PQ for x=5.1.

Let us find y-coordinate corresponding to x=5.1 for point P as:

y=5(5.1)=25.5

Now, we will use slope formula to find required slope.

m=\frac{y_2-y_1}{x_2-x_1}  

Let point (1,5)=(x_1,y_1) and point (5.1,25.5)=(x_2,y_2).

Using these points in slope formula, we will get:

m_{PQ}=\frac{25.5-5}{5.1-1}=\frac{20.5}{4.1}=5

Therefore, the slope of the line PQ is 5.

I need to graph -0.2x- 0.6y = 0.12
olga2289 [7]
This is under point slope intercept. so Ax+Bx=Cx. you can always change this to slope intercept which will be -.6y=.2x+.12 then give 1 a variable like 1 or 2 or something. then solve it, -.6y=.2+.12, -.6y=.32, y=-.53 so when x is 1, y is -.53. then make x 2 so -.6y=.52 so then when x is 2 y is -.86

Rational numbers are always,sometimes, never natural numbers?
SVETLANKA909090 [29]

Natural numbers are all whole, positive numbers. Like 1, 2, 3, 4, 5...

Rational numbers are numbers that can be expressed as a fraction, though they dont have to be a fraction.

Rational numbers are <u>sometimes </u>natural numbers.
