Answer:
y = -3x + 19
Step-by-step explanation:
Once you start graphing for this equation you will see that -5,4 is one of the points.
Isosceles triangle= 2 concurrent sides
Right angle= 90°
So which one has two concurrent sides and a right angle? A. The right angle is marked as well as the sides.
C has 2 concurrent sides, but it's not marked as a right angle. Option B has neither of these.
what is the situation to your question
Not always but it can happen although very doubtful
Those lines on the sides of x in the equation mean "absolute value". Which is a complicated way of saying "this number will never be negative". So if x = 2 then absolute value x= 2 but if x = -2 then absolute value x still is positive 2. Because of those brackets/lines (whatever they're called). So if you're given x=2 then it's simply saying y=4(2)-1 which is y=7
