Find the equation of the line containing the points (0,3) and (1,8)
Tema [17]

Answer:

y = 5x + 3

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

To calculate m use the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 3) and (x₂, y₂ ) = (1, 8)

m = \frac{8-3}{1-0} = 5

Note the line crosses the y- axis at (0, 3) ⇒ c = 3

y = 5x + 3 ← equation in slope- intercept form

Use the elimination method to solve the system of equations.<br><br>3x-5y= -16<br><br>2x+5y=31
Sholpan [36]
5x = 15
x = 3

3(3) - 5y = -16
9 - 5y = -16
5y = -16 - 9
5y = - 25
y = - 5

SOMEONE PLEASE HELP!!! ​HURRY
MAXImum [283]

Answer:

Slope of the line DV = -1

Step-by-step explanation:

Let point D (-5, 1) be (x_{1}, y_{1})

Let point V (-1, -3) be (x_{2}, y_{2})

m=\frac{y_2-y_1}{x_2-x_1}

Plug in the appropriate values,

m = \frac{-3-1}{-1-(-5)} = \frac{-4}{4} = -1

slope equals -1
