f(X)=-5X+4

# 2 Answers

f(x) = -5 + 4 is another way in saying..........

y = -5x + 4 > -5 is the slope and 4 is the y-intercept

The slope of the line passes through points (0, 4) and (2, -6) I chose those two points because the graph has even numbers. Just give x a value.

-5(2) + 4 = -6 > (2, -6)

-5(0) + 4 = 4 > (0, 4)

-5(2) + 4 = -6 > (2, -6)

-5(0) + 4 = 4 > (0, 4)

OK, I see the two places where the line passes. You assigned a value to "X"? Could you have chosen ANY number for "X"?

Yes! This graph have double digits. A single digit graph will have the same outcome. If

x = 1 then y = -1

-5(1) + 4 = -1 > (1, -1)

x = -2 then y = 14

-5(-2) + 4 = 14 > (-2, 14)

x = 3 then y = -11 > (3, -11)

The line will pass through all these points.

x = 1 then y = -1

-5(1) + 4 = -1 > (1, -1)

x = -2 then y = 14

-5(-2) + 4 = 14 > (-2, 14)

x = 3 then y = -11 > (3, -11)

The line will pass through all these points.
