The total price of the bicycle in Pierce county is $4136.24
An equation shows the relationship between two or more variables and numbers.
Let P represent the total price after taxes. The tax rate is 10.3% and the price of the bicycle is $3749.99. Hence:
Tax = 10.3% of $3749.99 = 0.103 * 3749.99 = $386.25
The total price (P) is:
P = $3749.99 + Tax = $3749.99 + $386.25
P = $4136.24
Therefore, the total price of the bicycle in Pierce county is $4136.24

The equation of the line is:
y + 4 = 5(x - 0) [point-slope form]
y = 5x - 4 [slope-intercept form]
<h3>How to Find the Equation of a Line?</h3>
Using the point-slope form, the equation of a line that has a slope of m, and passes through a point (a, b), can be written as: y - b = m(x - a).
Given the following:
Slope (m) = 5
Point on the line (a, b) = (0, -4)
Substitute m = 5 and (a, b) = (0, -4) into y - b = m(x - a)
y - (-4) = 5(x - 0)
y + 4 = 5(x - 0)
Or rewrite in slope-intercept form as:
y + 4 = 5x
y = 5x - 4

Answer:
3x + y = 9.5
Step-by-step explanation:
1) The equation of a line is in the form of y = mx + c, where m is the gradient and c is the y-intercept. Write the given values in that form.
y = -3x + c
2) Find the value of k by using the following formula: m = y2 - y1 / x2 - x1. We already know m.
-3 = 8 - k / k - 3
-3(k - 3) = 8 - k
-3k + 9 = 8 - k
-3k + k = 8 - 9
-2k = -1
k = -1/-2
k = 1/2
3) Therefore, a line with gradient of - 3 passes through the points (3, 1/2) and (1/2, 8). We can find the y-intercept (c). To do so, choose one of the coordinates and substitute.
y = -3x + c
1/2 = -3(3) + c
1/2 = -9 + c
1/2 + 9 = c
9.5 = c
Completed equation of the line: y = -3x + 9.5
4) Write it in the form of ax + by = c.
3x + y = 9.5
