Question

Given the linear equation y = 2x – 5, find the y-coordinates of the points (-2, ), (4, ), and (-1, ). Please show all of your work

Answer 1

simple but effective way to do it: place -2 where the x is and do the math. you will find y if x is -2 .... now do the same for the others and yull be good

Answer 2

for y coordinates set x =-2, 3, -1
for x = -2: y = 2(-2)-5 = -9 (-2,-9)
for x = 4: y = 2(4)-5 = 3 (4,3)
for x =-1: y = 2(-1)-5 = -7 (-1,-7)

Answer 3

give a man , or woman a fish, feed him/her for a day....

Answer 4

1) y=2x-5
y=2(-2) - 5
y=-4-5
y= -9

2)y=2x-5
y=2(4)-5
y=8-5
y=3

3)y=2x-5
y=2(-1)-5
y=-2-5
y=-7

Answer 5

great job and i think you did it on your own... right?lol

Answer 6

thanks how would i plot this

Answer 7

y = 2x -5
y = mx+b

m = 2 in this case which is the slope
b = -5 which is where the line hits the y axis

so you have starting at point 0,2 mark it then go up 2 and to the right 1

Answer 8

its the same method for all three
