Question

1. Find the slope of the line passing through the two given points
A(-1.4), -3. 7
​

Answer 1

Step-by-step explanation:

Equation of line that passes through points

(x1,y1)

and

(x

2,y2)

is given by

y−y1y2−y1=x−x1x2−x1

Hence equation of a line passing through

(2.7,

1.4)

and

(2.4,1.7)

is

y−1.41.7−1.4=

x−2.72.4−2.7

or

y−1.40.3

=

x−2.7−0.3

or

(y−1.4)=−x+2.7

(multiplying by 0.3 )

or

y = −x+4.1 ,

which is in slope intercept form

y = mx + c

, where m

is slope

Hence slope is
