The formula of a slope:

We have the points (look at the picture) (0, 1) and (-2, -2). Substitute:

 
        
             
        
        
        
9 3/4 = 39/4 mi/m
68 1/4 = 273/4 min
39/4 mutiply by 273/4 = 10647 / 16 mi = 665.4 mi
        
             
        
        
        
Hello!
To find the equation of a line parallel to y = 3x - 3 and passing through the point (4, 15), we need to know that if two lines are parallel, then their slopes are equivalent. 
This means that we create a new equation in slope-intercept form, which includes the original slope, which is equal to 3. 
In slope-intercept form, we need a y-intercept. So, we would substitute the given ordered pair into the new equation with the same slope and solve. 
Remember that slope-intercept form is: y = mx + b, where m is the slope and b is the y-intercept. 
y = 3x + b (substitute the ordered pair (4, 15))
15 = 3(4) + b (simplify) 
15 = 12 + b (subtract 12 from both sides) 
3 = b 
Therefore, the equation for the line parallel to the line y = 3x - 3, and passing through the point (4, 15) is y = 3x + 3. 
 
        
             
        
        
        
4250 millimeters.
Half of 8.5m is 4.25m.
4.25 m to mm is 4250.
