Answer 1

Answer:

y = 2x + 1

Step-by-step explanation:

• Slope-int form: y = mx + b
• m = slope or rise/run
• b = y-intercept

Given:

• Point (2, 5)
• m (slope) = undefined

When a slope is undefined, the line is a vertical line (it rises but doesn't "run").

To find m, use the given point's x-coordinate because the line you're trying to find will run vertically through that point.

• (x, y) = (2, 5); x = 2
• m = 2

Now the equation becomes y = 2x + b.

To find b, substitute the given point and the found slope into the formula, then solve for b.

• 5 = 2(2) + b
• 5 = 4 + b
• 5 - 4 = b
• b = 1

Now that you know what b is, you can substitute b into the equation:

• y = 2x + 1
