4.5a; changing from standard form to slope-intercept form

4.5a

Changing from standard form to slope-intercept form.

Change standard form first by adding/subtracting the "x" term.

4x + 2y = 14

-4x

2y = -4x + 14

Then Divide by the coefficient of the "y" value.

2y = -4x + 14

divide by 2

y = -2x + 7

Now the equation is in slope-intercept form

y = -2x + 7

Where the slope is -2

and the y-intercept is (0, 7)
