Finding x-intercepts and y-intercepts
Problem 1Find the x- and y- intercepts of the line x - 7y = 14.
Solution
1) To find y-intercept, you simply put x= 0 in the equation.
Then you get -7y = 14, so y= -2.
You may say that y= -2 is y-intercept,
or more accurately, that the point (0,-2) is y-intercept.
2) To find x-intercept, you simply put y= 0 in the equation.
Then you get x = 14.
You may say that x= 14 is x-intercept,
or more accurately, that the point (14,0) is x-intercept.
Problem 2What is the v-intercept and t-intercept for + = 9375 ?
Solution
To find t-intercept, take v=0 in the equation and find t
t = = = .
To find v-intercept, take t=0 in the equation and find v
v = = 25000.
