Shelley drew a line segment connecting point G (18,6) and point H (7,12) on a coordinate grid what is the length of GH

12.53 units to the nearest hundredth.

Step-by-step explanation:

The formula for this length = √[ (x2 - x1)^2 + (y2 - y1)^2 ]

GH = √[ (12-6)^2 + (7-18)^2 ]

= √ ( 36 + 121)

= √(157)

= 12.53 units.

sqrt( 157)

Step-by-step explanation:

To find the length of the line, we are finding the distance

d = sqrt( (y2-y1)^2 + (x2-x1)^2)

      sqrt( (12-6)^2 + (7 -18)^2)

      sqrt ( 6^2 + (-11)^2)

     sqrt( 36+121)

    sqrt( 157)

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

step-by-step explanation:

the answer is 128
