what is a equation in slope intercept (1,-3) and (4,6)

Question

what is the slope for (1,-3) and (4,6).

Answer 1

The points are and .

Slope intercept form line equation is y = mx + b,  where m is slope and b is y-intercept.

Slope

m = (6 - (-3)) / ( 4- 1 ) = 9/ 3 = 3

Line equation is y = 3x + b

Find the  y-intercept value by substituing any point in line equation.

6 = 3 * 4 + b

b = -6

Line equation is y = 3x - 6

 

Answer 2

The points are and .

Slope intercept form : .

Slope

Line equation is : .

Substitute the values and .

.

Therefore,Slope intercept form of a line is .
