Question

MEDAL AND FAN! ^^

-

Write the equation y - 4 = -2(x - 5) in slope-intercept form.

-

If you are finding the line perpendicular to x + 3y = 5, what is the slope of the line?

-

Write the slope-intercept equation of the line perpendicular to y = 5/2 x - 2, which passes though the point (0, 2).

-

Write the slope-intercept form of the equation parallel to y = 7x + 2, which passes through the point (1, -3).

-

Thank you so much! :) I really appreciate it.

Answer 1

for the first one simplify the equation into y=mx+b
second one, the slope of the line is the negative reciprocal of the slope of the given line
3rd, get the negative reciprocal of the slope of the given line and solve for the y-int using the given points
4th, parallel means that the slopes are same, so use the slope of the given line and solve for the y-int of the required line using the given points

Answer 2

@Data_LG2 he's right k
