What is the equation of the line that passes through (0,-3) and (2, 2)?
tigry1 [53]

Answer:

y = \frac{5}{2}x -3

Step-by-step explanation:

Given points (0,-3) (2, 2), we can start by solving for the slope of the line by using the formula:

m = \frac{y2 - y1}{x2 - x1}

Let (x1, y1) = (0,-3)

(x2, y2) = (2, 2)

Plug in these values into the slope formula:

m = \frac{y2 - y1}{x2 - x1} = \frac{2 - (-3)}{2 - 0} = \frac{5}{2}

Therfore, the slope of the line is \frac{5}{2}.

Next, we must determine the y-intercept of the line. By definition, the y-intercept is the y-coordinate of the point where the graph of the linear equation crosses the y-axis. The y-intercept is also the value of y when x = 0.

Using the slope (m) =  \frac{5}{2} and one of the given points, (2, 2), plug in these values into the  slope-intercept form, y = mx + b:

y = mx + b

y = \frac{5}{2}x + b

2 = \frac{5}{2}(2) + b

2 = 5 + b

Subtract 5 on both sides of the equation to solve for b:

2 - 5 = 5 + b - 5

-3 = b

The y-intercept (b) = -3.

Therefore, the equation of the line that passes through (0,-3) and (2, 2) is:

y = \frac{5}{2}x -3.

How do you find the missing dimension of a triangle
ki77a [65]

Answer:

The Pythagorean theorem states that a2 + b2 = c2 in a right triangle where c is the longest side. You can use this equation to figure out the length of one side if you have the lengths of the other two.
