Answer:
x-intercept: 7/6
Step-by-step explanation:
The x-intercept is found by solving for x when y=0.
0 = 6x -7
7 = 6x . . . . . add 7 to both sides of the equation
7/6 = x . . . . divide both sides by 6
The x-intercept is 7/6 = 1 1/6 ≈ 1.167.
__
The y-intercept is the constant in the given equation: -7. The slope of 6 tells you the line rises 6 units for 1 unit to the right. So, the point (1, -1) is another point on the graph. The line through those two points, (0, -7) and (1, -1), will intersect the x-axis at x=7/6.

<h3>Option c)Step-by-step explanation:
The alternate hypothesis use the sumbol for the population value
Let p be the proportion , Mean be and stadard deviation be
The null hypothesis states that population value is equal to the value mentioned in the given claim.
(by given).
The alternate hypothesis for the significance test states that the opposite of the null hypothesis(based on the claim )
∴
The symbol "<" because we want to test if the maze is completed faster and thus if the time has decreased.
<h3>∴ option c)
