WebExperienced Instructor in Prealgebra, Algebra I and II, SAT/ACT Math. Your equation is the slope-intercept form for a straight line. y = mx + b where m is the slope and b is the y-intercept. I think you can answer the question with this info. For further clarification, why not graph it on Desmos Graphing Calculator and confirm? WebThe slope-intercept form is y = mx+ b y = m x + b, where m m is the slope and b b is the y-intercept. y = mx +b y = m x + b Find the values of m m and b b using the form y = …
WebMar 1, 2015 · To find the y-intercept (b), you need to set x to one of the x values and y to one if the y values and solve: y=mx+b b=y-mx. The function could look like this: m=getSlope (x1,y1,x2,y2) b=y1-m*x1 return b. The coordinates of the point would be (0,b), so you can return that instead if you want. Share. Improve this answer.

Before using the calculator, it is probably worth learning how to find the slope using the slope formula. To find the equation of a line for any given two points that this line passes through, use our slope intercept form calculator.
WebIn the equation of a straight line (when the equation is written as " y = mx + b "), the slope is the number " m " that is multiplied on the x, and " b " is the y - intercept (that is, the point …
WebThe defintion of slope is $$ \text{slope} = \frac{\Delta y}{\Delta x} = \frac{y_2 - y_1}{x_2 - x_1}$$ where $(x_1,y_1)$ and $(x_2,y_2)$ are any two points on the line. So, if you let $(x_1,y_1) = (0,-3)$, and using the fact that the slope is 3, then any other point on the graph can be obtained by $$ 3 = \frac{y - (- 3)}{x - 0}$$ so $$ y = 3x - 3$$ how do lionfish stingWebThe y-intercept formula is used to find the y-intercept of a function. The y-intercept is mainly used in the process of graphing a function. Find the Y Intercept of the Graph Represented by the Equation x = y 2 +2 y-3. To find the y-intercept, we substitute x = 0 in the given equation and solve for y. Then, y 2 +2y-3 = 0 (y+3)(y-1) = 0 y=-3 how much potassium is in mangoWebThe forms y=mx+b and y=mx+a are essentially the same, except for the naming of the constant term. The form y=mx+b means slope m and y-intercept b; similarly, the form y=mx+a means slope m and y-intercept a. The form y=m (x-a) is essentially different from the other two forms, and means slope m and x-intercept (instead of y-intercept) a. how do lions avoid inbreedingWebNov 23, 2016 · With two points, we can define the slope of the line and, indeed, an equation for the line through those two points. Using your example, suppose the X-Intercept is 8 and Y-Intercept is 11. Then we know that ( 8, 0) and ( 0, 11) are points on this line. Therefore, the slope of the line is Δ y Δ x, or the change in y over the change in x. how do lions attract matesWebSlope intercept form is written as y = m x + b Take the point slope form equation and multiply out 7 times x and 7 times 2. y - 5 = 7 (x - 2) y - 5 = 7x - 14 Continue to work the … how do lions clean themselvesWebMath.
