Answer:
Yes
Step-by-step explanation:
To find the y intercept of this formula, you first need to convert it into slope intercept form.
x+y=1
y=-x+1
Here, the slope is negative 1 and the y intercept is (0,1). If you imagine the line with a slope of negative 1, it will indeed cross the x axis at (1,0). Hope this helps!
Answer:
Option B is right.
Step-by-step explanation:
Whenever a system of inequalities is given, normally we will get a collection of points that satisfy all the inequalities in the system
Option B is right
Option A is wrong because a single point cannot be a solution for all inequalities of a system normally an interval would be there
Option C is wrong since a single point if satisfies atleast one cannot be solution for the full system unless it satisfied all inequalities
Option D is wrong because satisfying atleast one inequality is not sufficient but satisfying all inequalities is a must.
