Question

What is the equation of a line that has a slope of `7` and a `y`-intercept of 2?

Answer 1

`y = color(red)(7)x + color(blue)(2)`

Explanation:

Use the slope-intercept formula to solve this problem.

The slope-intercept form of a linear equation is:

`y = color(red)(m)x + color(blue)(b)`

Where `color(red)(m)` is the slope and `color(blue)(b)` is the y-intercept value.

Substituting the values from the problem gives:

`y = color(red)(7)x + color(blue)(2)`
