Graph the linear equation y=x-3

1 answer:

7 0

Start with a dot on -3 of the y-axis, then use slope 1/1 to go up one and right one, do that until you reach 3 on the x-axis and make a dot, and then just draw a line through both dots.

What is an equation of the line that passes through the points (-4, -5) and (-8, -2)?

nikklg [1K]

Solution:

Step-1: Find the slope of the line.

Formula of slope: y₂ - y₁/x₂ - x₁

y₂ - y₁/x₂ - x₁ = Slope
=> -2 - (-5)/-8 - (-4) = Slope
=> -2 + 5/-8 + 4 = Slope
=> 3/-4 = Slope

Step-2: Use the point slope formula to determine the slope.

Point slope form formula: y - y₁ = m(x - x₁)

y - y₁ = m(x - x₁) = Equation of line
=> y - (-5) = -3/4{x - (-4)} = Equation of line
=> y + 5 = -3/4{x + 4} = Equation of line
=> y + 5 = -3x/4 - 3 = Equation of line
=> y = -3x/4 - 8 = Equation of line

The equation of the line is y = -3x/4 - 8.

The distance between two cities is 145 miles. A truck can cover this distance in 2. 5 hours. A car is 1. 5 times as fast as the

Sophie [7]

The relative speed of the car to the truck while moving towards each other is the sum of the speed of both vehicles.

The time it takes them to meet is 1 hour

Reasons:

The distance between the cities, d = 145 miles

The time it takes a truck to cover the distance = 2.5 hours

The speed of the car = 1.5 × Th speed of the truck

Required:

The time it takes them to meet if they are moving towards each other.

Solution:

$\displaystyle Speed = \mathbf{ \frac{Distance}{Time}}$

$\displaystyle Speed \ of \ the \ truck, \ v_{truck} = \frac{145 \ miles}{2.5 \ hours} = \mathbf{58 \ mph}$

Therefore;

The speed of the car, $v_{car}$ = 1.5 × 58 mph = 87 mph

At the time, t, the truck and the car meet, we have;

$\mathbf{v_{car} \times t + v_{truck} \times t = d}$

Which gives;

87 × t + 58 × t = 145

$\displaystyle t = \mathbf{\frac{145}{87 + 58}} = 1$

The time it takes them to meet, t = 1 hour
