(-3 0) (0 4) In Slope Intercept Form

Converting (-3, 0) and (0, 4) to Slope-Intercept Form

In this article, we will explore how to convert two points, (-3, 0) and (0, 4), into the slope-intercept form of a linear equation.

What is Slope-Intercept Form?

The slope-intercept form of a linear equation is a way of expressing a line in the form of y = mx + b, where:

  • m is the slope of the line (a measure of how steep it is)
  • b is the y-intercept (the point where the line crosses the y-axis)

Finding the Slope (m)

To find the slope, we need to use the two points given: (-3, 0) and (0, 4). We can use the formula:

m = (y2 - y1) / (x2 - x1)

where (x1, y1) = (-3, 0) and (x2, y2) = (0, 4).

m = (4 - 0) / (0 - (-3)) m = 4 / 3

So, the slope (m) is 4/3.

Finding the Y-Intercept (b)

Now that we have the slope, we can use one of the points to find the y-intercept (b). We can use the point (0, 4) and the slope (4/3) to find b.

y = mx + b 4 = (4/3)(0) + b 4 = b

So, the y-intercept (b) is 4.

The Slope-Intercept Form

Now that we have the slope (m) and the y-intercept (b), we can write the equation in slope-intercept form:

y = mx + b y = (4/3)x + 4

And that's it! We have successfully converted the two points (-3, 0) and (0, 4) into the slope-intercept form of a linear equation.
