What is the y-intercept in an equation? In an equation, the y-intercept is what y is equal to when x is 0. In a standard equation for a straight line such as y=mx+b, the y-intercept is equal to b. How do you find the Y-intercept? The y-intercept can be found by estimating...
Also when we refer to an equation of a line in slope-intercept form, which is we are always referring to the y-intercept. The y-intercept is the value of y where the line crosses when x=0. In our case, the it is already in the correct forn so we just have to pl...
Finding the x- and y-intercepts of an equation are important skills you'll need in math and the sciences. For some problems, this may be more complicated; fortunately, for linear equations it just couldn't be simpler. A linear equation will only ever have, at most, one x-intercept and ...
Simplify the equation. For example, the equation 2x + 5(0) = 10 would simplify to 2x = 10. Step 3 Divide each side of the equation by the multiplying factor of X. For example, in the equation 2x = 10, you would divide both sides of the equation by 2, leaving you the X-interce...
The y-intercept in this case is called an initial cost. b=600b=600 Write and Solve: Substitute the slope and intercept you defined into the slope=intercept equation. y=mx+by=55x+600y=mx+by=55x+600 Now we will answer the following questions: What is the total cost you’ve paid ...
Find an equation for the linear function which has y-intercept 4 and x-intercept 3? In the regression equation y = -2.3 + 3.5x, what is the intercept? Let y =x3/3+3x2-2x. Determine the x-intercept. Find the y-intercept. x + 3 y = 15. Find the y-intercept: f(x) = (x ...
Y-intercepts of a function lie where the graph intersects the y-axis. Since the point lies on the y-axis, the corresponding x-value must be 0, so in order to calculate the y-intercept from an equation, plug in 0 for x and solve for the corresponding y-value. ...
What is the (approximate) percentage increase in Q if both K and L increase by 10 percent, to K = 110 and L = 55? 11.25 Consider this equation for the demand for money: M = 250R−0.5L0.8, where M is the amount of money demanded, R is an interest rate, and Y is income. ...

To find the y-intercept, substitute the value of 'x' as 0 in the equation and solve for 'y'. On substituting 'x = 0' in the equation 3x + 5y =10, we get, 3(0) + 5y = 10 ⇒5y = 10 and thus y = 10/5 ⇒ y = 2 or 'b' = 2. Writing an Equation in The Slope ...
