Diagram shows two perpendicular straight lines,OB and CBD,drawn on a Cartesian plane.

Tems11 [23]

Answer: (a) y = -3x + 10

$\bold{(b)\x=\bigg(\dfrac{10}{3},0\bigg)}$

Step-by-step explanation:

The slope of line CD is perpendicular to line OB, which means they have opposite and reciprocal slopes.

Step 1: Find the slope of OB using the formula: $m=\dfrac{y_2-y_1}{x_2-x_1}$

(x₁, y₁) = (0, 0) and (x₂, y₂) = (3, 1)

$m=\dfrac{1-0}{3-0} = \dfrac{1}{3}$

Step 2: Find the slope of CD (opposite and reciprocal of OB)

$m = \dfrac{1}{3}\qquad m_\perp=-\bigg(\dfrac{3}{1}\bigg) = -3$

Step 3: Input the perpendicular slope and the slope into the Point-Slope formula: y - y₁ = m(x - x₁)

(x₁, y₁) = (3, 1) because it is the point the line will pass through

y - 1 = -3(x - 3)

y - 1 = -3x + 9 distributed -3 into (x - 3)

y = -3x + 10 added 1 to both sides

***********************************************************************

The x-intercept of DQ is the same x-intercept as CD. The x-intercept is when y = 0

y = -3x + 10

0 = -3x + 10

-10 = -3x subtracted 10 from both sides

$\dfrac{10}{3}=x$ divided both sides by -3

tristan rode his scooter from his home to his school. the following graph represents his trip, relating the time, x, to the dist

7nadin3 [17]

Answer:

1. Tristan road a total distance of 7 miles.

2. The part of the graph that is a horizontal line shows that Tristan traveled 0 miles for 15 minutes.

3. The slope of this graph can not be negative because total distance is not a negative number. Distance is a number that increases over time.

Step-by-step explanation:

Given the graph of Tristan's scooter trip from home to school, you can see that it is increasing for the first 10 minutes, constant for 15 minutes and increasing for another 10 minutes. This would indicate that he was moving at a steady pace the first three miles, then stopped to take a break/talk to friends for 15 minutes, and then rode the remaining 4 miles to school. Looking at the graph of miles versus minutes, you can see that after 35 minutes, he traveled a total of 7 miles and his break at mile 3 was from 10 - 25 minutes, or 15 minutes total. Distance is always a positive number, as it is not possible to travel negative miles.
