Exercise 28 Page 80

The slope of a line is the same as its rate of change.

-9/4

Practice makes perfect

Equations in slope-intercept form follow a specific format, where m represents the slope of the line and b is the y-intercept. y=mx+bLet's rewrite our equation a little bit so that it more closely resembles this format. This will make it easier to identify the features of the equation.

1/6y+3/8x=24

SubEqn

LHS-3/8x=RHS-3/8x

1/6y=-3/8x+24

▼

LHS * 6=RHS* 6

MultEqn

LHS * 6=RHS* 6

y=-3/8* 6x+24* 6

MoveRightFacToNum

a/c* b = a* b/c

y=-3* 6/8x+24* 6
