The function y=12x when plotted using the interval of
x-values from -1 to 3 will give a straight line on a given plot. Therefore the
function rule of a line y=mx+b can be used to describe the growth or
progression of this function. The rule states that y is directly proportional
to x.
Answer:
Step-by-step explanation:
I think it's the 2nd one
Slope = (10 - 5)/(-9 + 15) = 5/6
y = mx + b where m = slope and b = y-intercept
b = y - mx
b = 5 - (5/6) (-15)
b = 5 +12.5
b = 17.5
Equation y = 5/6 x + 17.5
Y-intercept = 17.5
X-intercept when y = 0
So
5/6 x + 17.5 = 0
5/6 x = -17.5
x = (-17.5) (6/5)
x = -21
Answer
Y intercept (0, 17.5 )
X intercept (-21 , 0)
If 22% are sixth graders, then the rest must not sixths graders.
100% of the school - 22% sixth grades = 78% are not sixths graders
