put the problem into the calculator and divide. so simple
Answer:

Step-by-step explanation:
y-intercept is when x = 0, so (0, 2)
x-intercept is when y = 0, so (4, 0)

Slope-intercept form of linear equation: 
(where m is the slope and b is the y-intercept)
Given:

- b = 2

X+y=9
y=8x
x+8x= 9
9x = 9
x = 9/9
x = 1
y = 8(1)
y =8
Answer:
4/3 units
Step-by-step explanation:
The distance can be found using the pythagorean theorem.
The y-distance is 4 - (-4), which is 8.
The x-distance is 1 - (-5), which is 6.
√(6² + 8³) 10 units.
