What is the equation of the line perpendicular to negative x plus y equals seven and passing through (-1 -1 )?

Hello:
the equation is : y = ax+b
the slope is a : a×(1) = -1( perpendicular to a line  : -x+y = 7   or y =x+7 with a slope of 1)
a =-1          y=-x+b
the line that passes through (-1, -1) : -1 =- (-1)+b
b =-2
 the equation is :  y  =-x-2

question: match the eqaution with its graph -8x - 5y = 40

answer: 8 x 5 = 40

x= absiss

y= orderly

so you have a proportional graph
