What is the equation of this second line? Parallel lines have the same slope. Solve for the slope in the first line by converting the equation to slope-intercept form. We can set up an equation in slope-intercept form and use these values to solve for the y-intercept. To solve, we will need to find the slope of the line. We know that it is parallel to the line given by the equation, meaning that the two lines will have equal slopes.

There are other ways to write the linear equation of a straight line than the slope-intersect form previously described. We've got a line with the slope 2. One of the points that the line passes through has got the coordinates 3, 5. It's possible to write an equation relating x and y using the slope formula with. Since we used the coordinates of one known point and the slope to write this form of equation it is called the point-slop form.

When graphing a line we found one method we could use is to make a table of values. However, if we can identify some properties of the line, we may be able to make a graph much quicker and easier. One such method is finding the slope and the y -intercept of the equation. This formula is known as the slope-intercept equation. If we know the slope and the y -intercept we can easily find the equation that represents the line. We can also find the equation by looking at a graph and finding the slope and y -intercept. Write the equation of the line in the graph by identifying the slope and y -intercept.

Q. Write the linear equation of the graph. 60 seconds. Q. What is the slope of the line perpendicular to y=(-5 /2)x+7.

What line is perpendicular to and passes through? The slope of this line is. The slope of the line perpendicular to this one will have a slope equal to the negative reciprocal. The perpendicular slope is. So the equation of the perpendicular line is. First, put the equation of the line given into slope-intercept form by solving for y. Line m passes through the points 1, 4 and 5, 2.
