Question

anonymous · Answer

-9(-2/3.1)-2(-2/3.1)=-7.10
So, no.

campbell_st · Answer

well simplify the equation

-11x = 8

substitute your value -2/3.1

so 

-11(-2/3.1) = 22/3.1

ok i really need some help with graphing this equation given the linear equation y=-1/2x+5, find the y-coordinates of the points (-6),(-2), and (8)

campbell_st · Answer

ok so sunstitute x = -6, -2 and 8

y = -(-6)/2 + 5 = 8
y = -(-2)/2 + 5 = 6
y = -(8)/2 + 5 = 1

you have the ordered pairs (-6, 8), (-2, 6) and (8, 1)

plot the points in the line plane and you should be able to draw one line that passes through all 3 points
