Question

Is there a way to find the x-coordinate of the x-intercept for y=3.7x-4.5, without using a graphing calculator?

Answer 1

yes; the x axis is the same line as the y=0 axis; which means that when y=0, we get the value of the x intercept

Answer 2

0 = 3.7x -4.5 ; add 4.5

4.5 = 3.7x ; /3.7

4.5/3.7 = x ; when y=0

Answer 3

simplified form is 45/37

decimal form is a repeater: 2.216......

Answer 4

So 4.5/3.7 is the answer for the x-coordinate and x-intercept?
