I'm assuming here that this line is a straight line. If so, it has the general equation
y=mx+c (where m= the gradient/slope and c is the intercept).
Substituting in the values provided in the question, we yield;
15= (9x9)+c
We then solve and rearrange;
15=81+c
15-81=c
-66=c.
Therefore, the slope intercept is -66
It is: y = mx+b whereas m is the slope and b is the y intercept
When it is a line through the origin.
y = 2x - 2
y = -5x+2 in slope intercept form
The slope intercept form is y = mx + c where the coefficient of y must be 1. Then c is the y-intercept ie the point (0,c) lies on the line.
Write the equation in slope-intercept form of the line that has a slope of 2 and contains the point (1, 1).
It is: y = mx+b whereas m is the slope and b is the y intercept
Write the equation of a line in slope-intercept form that has a slope of -2 and passes through the point (2, -8).
the slope of a line is 9/5 the y intercept is -4, express the equation of the line in point slope form
You use point-slope form to find the equation of a line if you only have a point and a slope or if you are just given two point. Usually you will convert point-slope form to slope-intercept form to make it easier to use.
When it is a line through the origin.
y = 2x - 2
Write an equation in slope-intercept form for the line that passes through the given point and is parallel to the given line (-7,3); x=4
Here is how to solve it. First, find the slope of the given line. To do this, solve the equation for "y". That will convert the equation to the slope-intercept form. From there, you can immediately read off the slope. Since parallel lines have the same slope, the line you are looking for will have the same slope. Now you need to use the point-slope form of the equation, with the given point, and the slope you just calculated. Finally, solve this equation for "y" to bring it into the requested slope-intercept form.
The slope intercept equation of a line is y=mx+b, where m is the slope of the line and b is the y-intercept.
The equation of a line in slope-intercept form is given by y = mx + b, where "m" represents the slope of the line and "b" represents the y-intercept.
y = -5x+2 in slope intercept form
