15 points! write the slope-intercept form of the equation of the line through the given point with the given slope. use y-y = m(x-x) to solve. through (2,5) slope= undefined

y = 2x + 1

Step-by-step explanation:

Given:

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.

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.

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

3: 2

step-by-step explanation:

shorter piece is 2: 3, so just reverse it, and you get 3: 2
