What does the y-intercept stand for in word problems? When x = 0, the corresponding y-value is the y-intercept. In the particular context of word problems, the y-intercept (that is, the point where x = 0) also refers to the starting value.

The standard form of a quadratic equation is written as y=ax2+bx+c, where x and y are variables and a, b, and c are known constants. To find the y-intercept from a quadratic equation, substitute 0 as the value for x and solve. The y-intercept is always equal to the value of c in the equation.

To graph an equation using the slope and y-intercept, 1) Write the equation in the form y = mx + b to find the slope m and the y-intercept (0, b). 2) Next, plot the y-intercept. 3) From the y-intercept, move up or down and left or right, depending on whether the slope is positive or negative.

So m isMoreFor. So if we just look at this m is going to be the coefficient on x right over there. So m is equal to 5 that is the slope. And b is just going to be this constant term plus 3 so b is equal to 3..
