Answer:
Here, m=-5/3, and b=y-intercept=20
Here, the y-intercept is: 20
Thus, option (d) is true.
Step-by-step explanation:
Given the equation
comparing the equation with the slope-intercept form
Here,
so the slope of the line is 3/5.
As we know that the slope of the perpendicular line is basically the negative reciprocal of the slope of the line, so
The slope of the perpendicular line will be: -5/3
Therefore, the point-slope form of the equation of the perpendicular line that goes through (15,-5) is:
simplifying the equation to convert it into the slope-intercept form
We know that the slope-intercept form of the line equatio is
here 'm' is the slope and 'b' is the y-intercept
subtract 5 from both sides
Here, m=-5/3, and b=y-intercept=20
Here, the y-intercept is: 20
Thus, option (d) is true.
