Find the equation of the line that passes through 0, -3 and -2, 5. Looking at the graph, you can see that this graph never crosses the y-axis, therefore there is no y-intercept either.

And they tell us that line A has an equation y is equal to 2x plus Note how we do not have a y. Let me do it in a better color. You may be wondering why this form of a line was not mentioned at the beginning of the lesson with the other two forms.

The process for obtaining the slope-intercept form and the general form are both shown below. This one is a little trickier.

The numerator tells us that the y value for the next coordinate increase by 5, the denominator tells us that the x value for the next coordinate changes by 1, so we can add this values to our starting coordinate of 0, Plug those values into the point-slope form of the line: Perpendicular lines cross each other at a degree angle.

Now you need to simplify this expression. You will NOT substitute values for x and y.

Now simplify this expression into the form you need. Parallel Lines and Their Slopes In other words, the slopes of parallel lines are equal.

Since you have a point and a slope, you should use the point-slope form of a line. You must know the structure of a straight-line equation before you can write equations for parallel or perpendicular lines. And this is the equation of the line in point slope form if you wanna put it in slope intercept form.

Since the slopes of perpendicular lines are negative reciprocals of each other, what do you think the slope of the perpendicular line is? A review of the main results concerning lines and slopes and then examples with detailed solutions are presented.

Find the equation of the line that goes through the point 4, 5 and has a slope of 2.Writing Linear Equations Given Two Points S LOPE -I NTERCEPT F ORM Write an equation in slope-intercept form of the line that passes through the points.

Write an equation, in the slope intercept form, of the line with slope -2 and passing through the point (-4, -5). Write an equation of the vertical line through the point (3, 0). Write an equation of the horizontal line through the point (7, -5). This is called the slope-intercept form because "m" is the slope and "b" gives the y-intercept.

(For a review of how this equation is used for graphing, look at slope and graphing.). I.

Write an equation in slope-intercept form of the line that passes through the given point and is parallel to the graph of the given equation. (1,-3; y + 2 – 4(x-1) /5(2). Equations of lines come in several different forms. Two of those are: slope-intercept form; where m is the slope and b is the y-intercept.

general form; Your teacher or textbook will usually specify which form you should be using. Perpendicular Line Calculator Find the equation of the perpendicular line step-by-step.
