The width of a rectangle is the length minus 3 units. The area of the rectangle is 40 units. What is the width, in units, of the rectangle?

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.

The correct answer is d, hope this
