Find an equation of the line that satisfies the given conditions.

How do you find an equation of a line that satisfies the given conditions?

The slope of the line y=−2x+5 is −2 . The opposite reciprocal of −2 is 12 , which is the slope of the perpendicular line. We also know that the line passes through the point (4,−10) . We can use the y=mx+b form of the line to determine the equation.

How do you find the equation of a line that passes through points?

Find the Equation of a Line Given That You Know Two Points it Passes Through. The equation of a line is typically written as y=mx+b where m is the slope and b is the y-intercept.

How do you find a line of a function?

Identify the slope, m. This can be done by calculating the slope between two known points of the line using the slope formula.Find the y-intercept. This can be done by substituting the slope and the coordinates of a point (x, y) on the line in the slope-intercept formula and then solve for b.

How do you find the equation of a line with one point and no slope?

If no slope is given we can let the slope = m .Given the point we can use the point-slope formula to write the equation for this problem. The point-slope formula states: (y−y1)=m(x−x1)(y−34)=m(x−−3)(y−34)=m(x+3)

How do you find the Y intercept?

How Do You Find the X- and Y-Intercepts of a Line in Slope-Intercept Form? To find the x-intercept of a given linear equation, plug in 0 for ‘y’ and solve for ‘x’. To find the y-intercept, plug 0 in for ‘x’ and solve for ‘y’.

How do you write an equation given two points?

Equation from 2 points using Slope Intercept FormCalculate the slope from 2 points.Substitute either point into the equation. You can use either (3,7) or (5,11)Solve for b, which is the y-intercept of the line.Substitute b, -1, into the equation from step 2.

How do you write an equation of a parallel line?

To find the slope of this line we need to get the line into slope-intercept form (y = mx + b), which means we need to solve for y: The slope of the line 4x – 5y = 12 is m = 4/5. Therefore, the slope of every line parallel to this line would have to be m = 4/5. Two lines are perpendicular if .

What is the Y intercept in an equation?

The equation of any straight line, called a linear equation, can be written as: y = mx + b, where m is the slope of the line and b is the y-intercept. The y-intercept of this line is the value of y at the point where the line crosses the y axis. © 2000-2005 All rights reserved.

What is linear function and examples?

Linear functions are those whose graph is a straight line. A linear function has the following form. y = f(x) = a + bx. A linear function has one independent variable and one dependent variable. The independent variable is x and the dependent variable is y.

What is straight line equation?
