Find the slope of the line.

i dont understand! will give !

Step-by-step explanation:

2,5 & 4,4

x1 = 4, y1 = 4  x2 = 2 , y2 = 5

change y/ change x

IMPORTANT: it is change in y over change in x, not the other way around. It will be wrong if done the other way, though that would seem to be more logical, since x is the first variable in the pair.

Y    4 - 5 = -1

X    4 - 2 = 2

-1/2

PLEASE MARK BRAINLIEST

Step-by-step explanation:

The slope of a line passes through two points (a,b) and (c,d) is given by :-

From the give graph, the line is passing through (4,4) and (2,5).

Then the slope of line will be :-

Hence, the slope of the line on the graph

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)

ratio is 2 : 9

the answer is three

13.5 : 3
