Question

Choose an equation in slope-intercept form for the line that passes through (-8,1) and is perpendicular to the y=2x-17.

Choose one answer.
a. y= -2x+1
b. y= -(1/2)x - 5
c. y= -(1/2)x - 3
d. y= -2x - 4

Answer 1

Slope of perpendicular lines = opposite reciprocal
the slope of y = 2x - 17 is 2 or 2/1.

we using opposite reciprocal
opposite reciprocal a/b is -b/a

2/1 would change into -(1/2)
now, input the value x and y,
and the answer is c. y = -(1/2)x -3

hope this help
