Question

Graph the function f(x)=−13x+1. Use the line tool and select two points to graph.

Answer 1

just took the test, got it wrong but here it is

Explanation:

Answer 2

(See attached image)

Explanation:

Replace f(x) with y

y = -13x + 1

Choose values for x, then plug in to find y.

x = 0 ---> y = -13(0) + 1

y = 0 + 1

y = 1

Therefore a coordinate point on the line is (0,1)

To graph, start at the origin (0,0) and move 1 unit up

x = 1 ---> y = -13(1) + 1

y = -13 + 1

y = -12

Therefore a second coordinate point on the line is (1, -12)

To graph, start at the origin (0,0) and move 1 unit to the right and then 12 units down.

Connect both points and extend the line in both directions.
