Final answer:

The equation for the line that passes through the coordinates (2,0) and (0,3) in y-intercept form is y = (-3/2)x + 3.

Step-by-step explanation:

To find the equation in y-intercept form, we need to determine the slope and the y-intercept of the line passing through the given coordinates.

Slope (m) = (y2 - y1) / (x2 - x1) = (3 - 0) / (0 - 2) = -3/2

Using the slope-intercept form, y = mx + b, where m is the slope and b is the y-intercept, we can substitute the values into the equation:

y = (-3/2)x + b

To solve for b, we can substitute the coordinates of either point into the equation. Using (2, 0):

0 = (-3/2)(2) + b

b = 3

Therefore, the equation in y-intercept form is y = (-3/2)x + 3.
