Which ordered pair makes both inequalities true?y > –2x 3y < x – 2?
grin007 [14]
Whatever your choices are, just substitute the x and y values to the equations. If they satisfy the inequality, then they are the solutions. For example, point (7, 1) satisfies the inequalities.

y > -2x
1 > -2(7)
1 > -14 (true)

<span>3y < x – 2
3(1) < 7 - 2
3 < 5 (true)

I hope I was able to help you. Have a good day.</span>

A line perpendicular to the line y=1/2x+5 with y-intercept -2
mash [69]
Y = 1/2x + 5...slope here is 1/2. A perpendicular line will have a negative reciprocal slope. All that means is " flip " the slope and change the sign. So our perpendicular slope is -2/1 or just -2 (see how I flipped the slope and changed the sign)

y = mx + b
slope(m) = -2
y int (b) = -2

so ur equation is : y = -2x - 2
