Find the equation of a line that is perpendicular to the line y = x + 7 and has the same y-intercept as 3y = 2x - 9. state the answer in standard form.

The standard for is x + y = -3

Step-by-step explanation:

To start, we know that the slope of perpendicular lines are opposite and reciprocal. Since the perpendicular line has a slope of 1, we know the new line will have a slope of -1.

To find the intercept of the second equation, solve for y and look for the constant.

3y = 2x - 9

y = 2/3x - 3

This gives us an intercept of -3.

Now that we have the slope and intercept we can use slope-intercept form and plug in the information. Then we simply need to solve for the constant.

y = mx + b

y = -x - 3

x + y = -3
