Write the equation of a line in slope-intercept form that is perpendicular to the line y= 3/5 x - 1 and passes through the point (-9, 4). write the equation of a line in slope-intercept form passing through (4, 5) and (6, 8)

3) Option C

4) Option C

Step-by-step explanation:

Question 3:

A line perpendicular to another line has a slope which is a negative reciprocal of the line which is perpendicular to it.

So the slope of its perpendicular line will be .

The standard slope intercept form of an equation of a line is .

Therefore, the equation of a line perpendicular to the given equation is

Question 4:

Therefore, the equation of a line passing through (4, 5) and (6, 8) is
