Complete the equation of the line through (3,-1) and (4,7)

Answers

Answer 1
firstly , we must find the gradient.

gradient, m = y2 - y1 / x2 - x1

m = 7 - (-1) / 4 - 3
m = 8

a straight line is y=mx+c
thus, we have to find the c which is y-int by subs one of the coordinate to the equation.

y=mx + c
7=8(4) + c
c = -25

thus the equation is y = 8x - 25
Answer 2




The answer would be Y=8x-25

Answers

Answer:8.06

Step-by-step explanation:

4 x 4= 16 7 x 7 = 49

49+16=65

square root of 65 =8.06

Answer:

[tex] \sqrt{65} [/tex]

Step-by-step explanation:

To find the hypotenuese of a right angle you use the pythagreon theroem.

[tex] {a}^{2} + {b}^{2} = {c}^{2} [/tex]

a and b are the height and base, while c is the hypotenuese. simply insert the values in the equation and find the variable.

[tex] {4}^{2} + {7}^{2} = {c}^{2} \\ 16 + 49 = {c}^{2} \\ 65 = {c}^{2} \\ \sqrt{65} = c[/tex]

The radical form answer is above, otherwise it would be a decimal.

Step 1: 8x − 9 = 1; Step 2: 8x = 10

Step 1: 15x − 20 = 1; Step 2: 15x = 21

Step 1: 15x − 4 = 1; Step 2: 15x = 5

Answers

9514 1404 393

Answer:

  (C)  Step 1: 15x − 20 = 1; Step 2: 15x = 21

Step-by-step explanation:

The first step is to eliminate the parentheses, using the distributive property.

  5(3x − 4) = 1

  15x -20 = 1

The second step is to add 20 to both sides of the equation.

  15x = 21

This pair of steps is shown in the 3rd choice.

_____

Comment on the answers

The distributive property seems to be applied incorrectly a lot of the time. Here, you can choose the correct answer by looking at the result of properly applying the distributive property: 5(3x-4) = 15x-20. Only the correct choice has this as the first step.
