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.
