Question

Who’s is the graph of Y is greater than or equal to

1 - 3x?

Answer 1

the first graph

Explanation:

y ≥ 1 - 3x

y ≥ - 3x + 1

y intercept is 1 or (0, 1)

Slope is -3/1 or down 3 and right 1 from y intercept

that's the graph of the line, now to deal with the inequality part

so ≤or ≥ make the line solid and < or > makes it dotted. so here its ≥ so its a solid line. That only leaves the 1st and 3rd.

now we test a point not on the graph. If the point makes it true then we shade on the side of the point. We usually use (0,0).

y ≥ - 3x + 1 now plug in (0, 0)

0 ≥ -3(0) + 1

0 ≥ 0 + 1 this is untrue so (0,0) is not shaded or that whole side.

so its the first graph

Answer 2

Probably the 2nd last question but please elaborate by what you mean by the question
