it reads...
write the equation for a line that is perpendicular to the given line and goes through the given point. write your equation in slope-intercept form and then in standard form.
the question.
y=5x=9, (-5,5)

The given equation is in slope-intercept form. This means that we can read off the slope of this line by examining the equation; no calculations are needed to see the slope of the given line.

Please let us know if you cannot determine the slope of the given line.

Perpendicular slopes are negative reciprocals of each other.

EG1:

Given slope is -4.

Perpendicular slope is 1/4.

EG2:

Given slope is 2/3.

Perpendicular slope is -3/2.

After you determine the perpendicular slope, then use it with the given coordinates to write the equation of the required line using the point-slope form. (This is the form that we use when we know the line's slope and the coordinates of one point.)

y - y1 = m (x - x1)

Solve the point-slope form for y to get the slope-intercept form.

y = mx + b

Standard form has the x- and y-terms on the left side of the equal sign and the constant term on the right side.

ax + by = c

Please show your work if you need more help with this exercise.
