What is the slope of the line perpendicular to the graph -7x+y=1 a. -7 b. 1/7 c. [in bold] 1/7 d. 7

perpendicular slope = -

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y-intercept )

rearrange - 7x + y = 1 into this form

add 7x to both sides

y = 7x + 1 ← in slope- intercept form

with slope m = 7

given a line with slope m then the slope of a line perpendicular to it is

= - = -
