Question

Write an equation in slope-intercept form of the line satisfying the given conditions.
Through (-7, -9), perpendicular to 4x - 5y = 2

Answer 1

5x+4y+71=0

Answer 2

4x - 5y = 2
5y = 4x - 2
y = (4/5) x - 2/5
slope = 4/5 so slope of a line perpendicular to this line = -5/4
the reqd. line also passes thru (-7,-9)
using y-y1 = m(x-x1):
y- -9 = -(5/4) (x - -7)
y+9 = -(5/4)x - 35/4
y = (-5/4)x - 71/4

Answer 3

y=(-5/4)x+(-71/4)

Answer 4

-71/4 should be in brakets
