Evaluate -y+(-z)+7.99−y+(−z)+7.99minus, y, plus, left parenthesis, minus, z, right parenthesis, plus, 7, point, 99 where y = 1.46y=1.46y, equals, 1, point, 46 and z = 3.82z=3.82z, equals, 3, point, 82.

step-by-step explanation:

for the free

graph b

step-by-step explanation:

one solution- graph a (clear intercepting point.)

no solution- graph b (they're parallel, there will never be a point of interception.)

infinite solutions- graph c (all points intercept.)
