line l passes through two points (-2,1) and (4,3) then find the slope of line l and find y-intercept of the line l ,find x-intercept of the line l and write the equation of the line l and sketch the graph of the line i

Respuesta :

The linear equation that passes through the two given points is:

y = (1/3)*x + (5/3)

How to find the linear equation?

A linear equation is written as:

y = a*x + b

Where a is the slope and b is the y-intercept.

If a line passes through two points (x₁, y₁) and (x₂, y₂), then the slope is equal to:

a = (y₂ - y₁)/(x₂ - x₁).

In this case, we know that the line passes through (-2, 1), and (4, 3).

Then the slope is:

a = (3 - 1)/(4 - (-2)) = 2/6 = 1/3

So the line is something like:

y = (1/3)*x + b

To find the value of b, we use the fact that the line passes through the point (4, 3), then:

3 = (1/3)*4 + b

3 - 4/3 = b

5/3 = b

So the line is:

y = (1/3)*x + 5/3

Finally, the x-intercept of the line is the value of x such that y = 0.

0 = (1/3)*x + 5/3

-5/3/(1/3) = x = -5

The graph of the line can be seen below.
