The line passes through (4,0)
And has a slope of 0.5
Taking another point (x,y) along the line;
Slope = change in y-axis ÷ change in x-axis
0.5 = (y - 0) / (x - 4)
y = 0.5x - 2
The answer is X2-10X+21
Explanation: If u put the equation in the graphing calculator 3 and 7 both equal zero meaning they are the x’s of the situation.
Hello! In order to find a linear function without graphing it, we can see if the x-values (domain) has more than one value of y (range) out of this set of ordered pairs. Those ordered pairs represent a linear function, because each x-value does not have more than 1 y-value. Therefore, those points satisfies a function.
Answer:
You're right- I'm pretty sure it's C.
