Slope intercept form:
y=mx+b
Where:
m= slope
b= y-intercept
For: y=1/2x-2
slope = 1/2
b= -2
To graph it we have to look at the y-intercept.(-2) It means that the line crosses the y axis at y=-2.
looking at the slope, we know that slope = rise (y) / run (x). 1/2
For every 2 units along the x-axis (to the right) the line goes up by 1 unit.
Since inequality has a y> the line is not included in the solution, so it's a dashed line, where the solution is above the line.
Answer:
x = 33.33 kilometers
Step-by-step explanation:
you could make use of the percent, base, and rate formula here. we know that 15% is the rate, 5 kilometers is the percent, therefore what we are looking for is our base.
; cross multiply.
15x = 500
x = 33.33 kilometers
therefore, the race is 33.33 kilometers.
