<span>x-axis: hours in increments of 1; y-axis: miles in increments of 5
You always want the constant numbers such as time on the x-axis
And since your y values are all large numbers and multiples of 5, it makes sense to use increments of 5</span>
a. 4/5 because
the equation to find slope is
y2-y1 divided by x2-x1
which is -5-(-1) divided by -2-3 which is -4/-5 which is 4/5.
I think the answer is 8/25, 38%, .41
Y = <span>b^x
when x = 1
y = b^1
y = b
Therefore, the value of b is the same as the value of y when x =1
From the graph,
When x = 1, y = 0.5
Therefore, b = 0.5
To confirm this
From the graph,
When x = -1, y = 2
Since </span>y = b^x<span>
2 = </span>b^-1
2 = 1/b
2b = 1
b = 0.5
When x = -2, y = 4
Since y = b^x
4 = b^-2
4 = 1/(b^2)
b^2 = 1/4
b = √(1/4)
b = 1/2
b = 0.5
Therefore, it is conformed that b = 0.5
