Question

What is the slope of a line that is perpendicular to the line whose equation is 7x−3y=10?

Answer 1

Since this equation is already in standard form, there is no need to convert it. Standard form is Ax + By = C. In this equation, 7 = A, 3 = B, and 10 = C. From standard form, Ax + By = C equals negative A over B.

7x + 3y = 10

↓

`\displaystyle\ m= (-7)/(-3)`

Then you'd simplify.

`\displaystyle\ m=(7)/(3)`

The slope cannot be simplified any more, so this would be the final answer.
