Answer:
(2,-1)
y= -1
x= 2
Step-by-step explanation:
y= -2x+3
4x-3y=11
substitute the value of y into an equation
4x-3(-2x+3)=11
distribute by multiplying numbers in parenthesis by -3
4x+6x-9=11
add 4x to 6x
10x-9=11
add 9 from both sides
10x=20
divide both sides by 10
x=2
substitute the value of x into an equation
y= -2•2+3
multiply -2 to 2
y= -4+3
add -4 to 3 but 4 is negative, so subtract
y= -1

Answer:
-1/3
Step-by-step explanation:
y2-y1 divided by x2-x1
6-8=-2(y slope)
4--2=6(x slope)
-2/6=-1/3 or -0.3333
Half of 23 would 11.5 and you had to do was divide 23 by 2
