Question

Find the slope of the line that passses thruogh 1,5 and 10,9

Answer 1

Answer: The slope is 4/9 or -4/-9.

Explanation:

(1,5)

(10,9) Find the difference in the y values and divide it by the difference in the x values.

5-9= -4

1- 10= -9

-4/-9= 4/9

so the slope is 4/9

Using the slope we could also find the y-intercept and write the equation.

5=4/9 (1) + b where b is the y-intercept

5= 4/9 + b

-4/9 -4/9

b= 41/9

Now we will have the equation y= 4/9 + 41/9
