Hello : let  A(1;5) and B(-2;14)
the equation is y = ax+b   .... a is a slope
a = (yb -ya)/(xb -xa)
 a = (14-5)/(-2-1)
a = -3
 y = -3x+b 
A passes <span>through</span>  the line :  5 =-3(1)+b .....         b = 8

What is 4/5 of 20.5?
earnstyle [38]
To find 4/5 of 20.5 the first step is to convert 4/5 into a decimal. You can do that by dividing 4 by 5. 
4/5 is .8 so your equation would now be .8 of 20.5 
"of" states that you are multiplying, so .8 times 20.5 is 16.4
4/5 of 20.5 is 16.4

(08.02)a pair of equations is shown below. 3x − y = 9 y = −2x + 11 if the two equations are graphed, at what point do the lines
mixas84 [53]
3x - y = 9
y = -2x + 11

3x - (-2x + 11) = 9
3x + 2x - 11 = 9
3x + 2x = 9 + 11
5x = 20
x = 20/5
x = 4

y = -2x + 11
y = -2(4) + 11
y = -8 + 11
y = 3

solution (where the lines intersect) is (4,3)
