How do you find the coordinate when given the slope?

The slope formula is m=(y2-y1)/(x2-x1), or the change in the y values over the change in the x values. The coordinates of the first point represent x1 and y1. The coordinates of the second points are x2, y2.

How do you find the y-intercept with the slope and a point?

Using the “slope-intercept” form of the line’s equation (y = mx + b), you solve for b (which is the y-intercept you’re looking for). Substitute the known slope for m, and substitute the known point’s coordinates for x and y, respectively, in the slope-intercept equation. That will let you find b.

How do you calculate the y-intercept?

When an equation is not in y = mx + b form, we can solve for the intercepts by plugging in 0 as needed and solving for the remaining variable. To find y-intercept: set x = 0 and solve for y. The point will be (0, y). To find x-intercept: set y = 0 and solve for x.

How do you find a missing slope?

Given two points, one which has a missing value, and the slope of a line, you can find the missing value by using the slope formula: m=(y2-y1)/(x2-x1).

How to find a missing coordinate of a point on a line?

But if we already know the slope of a line, we can use the slope formula to find a missing coordinate of a point on the line. Here’s the slope formula we’ll be using: Example Find x if the line through the points (6, x) and (1, -5) has a slope of 2. Since the slope of the line is 2, we’ll replace the m in our slope equation with 2.

How to find the slope of a line using coordinates?

Find the slope of a line that passes through points A and B. Formula : Slope m = yB − yA xB − xA Slope m = y B – y A x B – x A. Solution: Slope m = 10 − 2 7 − 3 Slope m = 10 – 2 7 – 3. = 8 4 = 8 4. m = 2. Slope calculator uses coordinates of two points A(xA,yA) A ( x A, y A) and B(xB,yB) B ( x B, y B) in the two-dimensional Cartesian coordinate

How do you find another point with a slope of 3?

Slope = change in y change in x = rise run Therefore, if we are given a slope of 3, we can assume that it means a change in y of 3 for every change in x of 1. So, if we want to find another point on the line that (2, −4) makes with a slope of 3, then we can simply add 1 to the x, and 3 to the y: (2, − 4)

How do you find the slope of an undefined line?

Undefined slope, if a line y = mx + b y = m x + b is vertical. This is because division by zero leads to infinities. So, the equation of the line is x = a x = a. All vertical lines x = a x = a have an infinite or undefined slope.
