Points (-2,1) and (3,y) have a slope of -3 find the y coordinate of the point

To find the y-coordinate of the point (3, y), we can use the slope formula:

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

Using the given information, we can write the equation as:

-3 = (y - 1) / (3 - (-2))

Simplifying the denominator:

-3 = (y - 1) / 5

Cross-multiplying:

-15 = y - 1

y = -15 + 1

y = -14

Therefore, the y-coordinate of the point (3, y) is -14.
