How do you write an ordered pair equation?
Ordered pairs are often used to represent two variables. When we write (x, y) = (7, - 2), we mean x = 7 and y = - 2. The number which corresponds to the value of x is called the x-coordinate and the number which corresponds to the value of y is called the y-coordinate. Example 1.
How do you write a linear equation using ordered pairs?
Step 1: Start with the slope–intercept form of the line, y = m x + b . Step 2: Substitute the value of the slope for. Step 3: Substitute the coordinates (–2, 3) into the equation for the variables and. Step 4: Solve for.
What distance in kilometers corresponds to 20 miles?
32.2 km corresponds to 20 miles.
How do you write an equation of the line that passes through the given point and has the given slope?
These are the two methods to finding the equation of a line when given a point and the slope:.
Substitution method = plug in the slope and the (x, y) point values into y = mx + b, then solve for b. ... .
Point-slope form = y − y 1 = m ( x − x 1 ) , where ( x 1 , y 1 ) is the point given and m is the slope given..
