# How to write a slope intercept equation parallel

### Writing equations of parallel and perpendicular lines worksheet Point-Slope Form Parallel, Perpendicular Lines Purplemath Straight-line equations, or "linear" equations, graph as straight lines, and have simple variable expressions with no exponents on them. We know that y represents cost, and we are given a cost and asked to find the number of months related to having spent that much.

There is, ironically, no standard definition of "standard form". I like slope-intercept form the best. We will interpret a word problem, write a linear equation from it, graph the equation, interpret the y-intercept and make a prediction. Provided by: Lumen Learning.

### Slope intercept form

Nowadays, you likely needn't worry too much about the "standard" forms; this lesson will only cover the more-helpful forms. I like slope-intercept form the best. There is, ironically, no standard definition of "standard form". Point-Slope Form Parallel, Perpendicular Lines Purplemath Straight-line equations, or "linear" equations, graph as straight lines, and have simple variable expressions with no exponents on them. If you see an equation with only x and y — as opposed to, say x2 or sqrt y — then you're dealing with a straight-line equation. How do you do that? In the slope-intercept form of a straight line, I have y, m, x, and b. Authored by: Tyler Wallace. When you know the slope and the y-intercept of a line you can use the slope-intercept form to immediately write the equation of that line.

When lines in a plane are parallel that is, they never crossthey have the same slope. How accurate do you think this model is?

## Find the equation of the line that is perpendicular to this line and passes through the point

How do you do that? There are different types of "standard" formats for straight lines; the particular "standard" format your book refers to may differ from that used in some other books. Just plug in your x-value; the equation is already solved for y. Affiliate Common exercises will give you some pieces of information about a line, and you will have to come up with the equation of the line. I like slope-intercept form the best. We are to use y to represent cost, and x to represent the number of months we have used the phone. Provided by: Lumen Learning.
