Answer:
108 miles
Step-by-step explanation:
Given the points (0.5, 135) and (2,81)
Diatnce between two points :
D = √(x2 - x1)² + (y2 - y1)²
X1 = 0.5 ; y1 = 135 ; x2 = 2 ; y2 = 81
D = √(2^2 - 0.5^2) + (81^2 - 135^2)
D = √(4 - 0.25) + (6561 - 18225)
D = √3.75 −11664
D = 107.98263
D = 108 miles
A. equation: y = -3x - 2
B. y-intercept: -2
<em><u>Solution:</u></em>
Given that,
<em><u>Write the equation 12x = - 4y - 8 in slope-intercept form</u></em>
The slope intercept form is given as:
![y = mx + c](https://tex.z-dn.net/?f=y%20%3D%20mx%20%2B%20c)
Where,
m is the slope and "c" is the y intercept
From given
![12x = -4y - 8\\\\Rewrite\\\\-4y-8 = 12x\\\\Move\ the\ constant\ to\ right\ side\\\\-4y = 12x + 8\\\\y = \frac{12x}{-4} + \frac{8}{-4}\\\\y = -3x -2](https://tex.z-dn.net/?f=12x%20%3D%20-4y%20-%208%5C%5C%5C%5CRewrite%5C%5C%5C%5C-4y-8%20%3D%2012x%5C%5C%5C%5CMove%5C%20the%5C%20constant%5C%20to%5C%20right%5C%20side%5C%5C%5C%5C-4y%20%3D%2012x%20%2B%208%5C%5C%5C%5Cy%20%3D%20%5Cfrac%7B12x%7D%7B-4%7D%20%2B%20%5Cfrac%7B8%7D%7B-4%7D%5C%5C%5C%5Cy%20%3D%20-3x%20-2)
Thus the slope intercept form is found
Comparing with y = mx + c ,
c = -2
Thus the y intercept is -2
