Question

Algebra 2 question. Only one question, please help!!!!!!!!!!!

Answer 1

Treat the solid black line as a regular equation first. Find the slope using the slope formula, and the y-intercept

Since we have a solid line with the shading above, replace y = with y ≥

Answer 2

I have been doing this kind of work for a few days and I still don't understand how to get the equation

Answer 4

For finding equation of the line you have to find its gradient okay


Formula for gradient is (y2-y1)/(x2-x1)


Take any 2coordinates set from graph line


For coordinate the first in the bracket is x-coordinate while the right one is y-coordinate (x-coordinate ,y-coordinate)

Like in this question when x-coordinate (see horizontally) is 2; the y-coordinate is (see vertically where is the line ) also 2





So one coordinate of line is (2,2)



See another (0,-6)



So your coordinates are
(X1,y1) ; (x2,y2)
(2,2) ; (0,-6)

So put the values in gradient
y2=-6
y1=2
x2=0
x1=2
Gradient= (-6-2)/(0-2) =4



For finding equation the formula is
y-y1 = m(x-x1)

In this m=gradient
And x and y will remain x and y

Put values in equation
y-2=4(x-2)
Simplify
y-2=4x-8
y=4x-8+2
y=4x-6
So this is the equation

y=4x-6


So as vocaloid said replace y= with y ≥

Your answer for this question will be

y ≥ 4x-6
