Answer:
a) the slope is 2/-1 or just -2
b) the slope is 1/1 or just 1
Step-by-step explanation:
You can find slope (rise/run) by picking a point on the graph. For example on question a I chose the point (-2, 1) i then counted how far my run was, which is 2, and my rise (or how far down it went) was -1. Therefore my slope was 2/-1 or just -2.

Answer:
x=9 y=5
Step-by-step explanation:
Let -4x+9y=9 be function 1 while x-3y=-6 be function 2
function 1 plus 4 times function 2
-4x+4x+9y-12y=-15
Simplify
-3y=-15
Divide each side by -3
y=5
Substitude y=5 into function 2
x-3(5)=-6
x-15=-6
add 15 to each side
x=9
