At-shirt that usually cost $32 is on sale 1/4 off. what is the sale price? ?

You know that 1/4 --> 25 %.

So

32 --> 100%
x  --> 75 %



Therefore The sale price is $24.

Hope this helps !

Zero is the mid point of the line segment

Where m is the slope of the line and b is the y-intercept of the line, or the y-coordinate of the point at which the line crosses the y-axis. to write an equation in slope-intercept form, given a graph of that equation, pick two points on the line and use them to find the slope. this is the value of m in the equation.
