According to Cost Helper, the cost for a single-coat synthetic enamel paint job ranges from $300 to $900, with an average of $566. A mid-level paint job with a higher-quality paint and additional prep work like removing rust and dents can range from $1,000 to $3,500 with an average of $1,316. For a high-quality paint job drivers reported spending between $2,400 and $7,500, with an average price of about $5,000. Kuehn says the average price he charges to completely paint a car is between $600 and $1,000, which he says is below the national average. He says most full paint jobs cost around $2,000.
Quick Answer. Y = mx + b is the equation for a straight line. B is the point value of where the line intercepts the y axis, called the y intercept. M is the value of the slope of the line. X is the value where the line intercepts the x axis.
If the equation of a line through the origin is $y=mx$, then the line $y=mx+b$ is the same as $y-b=mx$. If we put $y'=y-b$ then this second line is $y'=mx$, and with $y=y'+b$ we see that the original line is shifted by $b$ units in the $y$ direction. Others have drawn the diagram.
