Find the slope of a line parallel line to each given line. Y=-10x+5

2 answers:

8 0

Hello!

Any line parallel to the line of y = -10x + 5 will have a slope of 10.

Any line parallel to another line will always have the same slope. The only thing that changes is the y intercept, also know as the ‘b’ or the initial value.

I hope I helped!

Let me know if you need anything else!

The answer should be - 10.

Y = - 10x + 5 is presented in the slope-intercept form. Also known as y = mx + c. M is the slope, and c is the place (y value) where the line cuts at the y-axis.

Remember that 2 parallel lines must have the same slope with each other.

Therefore, since m is the slope and the line is parallel to each other, the answer should be - 10, just answer with the number in the place m of the equation of straight line.

Find the equation of the line parallel to the line y = 4x – 2 that passes through the point (1, 5).

Answer:

4x-y+1=0

Step-by-step explanation:

here,given equation of a line id

4x-y-2=0.. eqn(i)

equation of any line parallel to line (i) is

4x-y+k=0...eqn(ii)

since, the line(ii) passes through (1,5)[replacing x=1 and y=5 in eqn(ii), we get]

4*1-5+k=0

or, 4-5+k=0

or,-1+k=0

•°•k=1

substituting the value of k=1 in eqn(ii),

4x-y+1=0 is the required equation of the line.

When you are given three side lengths for a triangle, how do you know which length to substitute for a, b, or c in the Pythagore

Romashka [77]

Answer:

When Sum of square of two Sides is equal to square of third side of triangle.

Step-by-step explanation:

Given:

Three side length of triangle are given we need find the which value to substitute for a, b, c in Pythagoras theorem.

First we will find the squares of all length, then we will check which two square of side are equal to square of third side as per Pythagoras theorem.

Hence the two side would according be a and b and third side will become c.

For example if length of triangle is given as 6 cm, 8 cm and 10 cm.

We will first take square of all

$6^2=36\\8^2=64\\10^2=100$

Now we can see that

$36+64=100\\6^2+8^2=10^2$

Now by Pythagoras theorem.

$a^2+b^2=c^2$

Hence we can say a = 6 cm, b = 8 cm, c= 10 cm
