Y=x^2-4 330266-Y x 2 4x 5

`y4=4(x2)` `y=4x84` `y=4x4` (1) Thus the slope is 4 and the y intercept is 4 The standard form of a line is axby=c Add 4x to both sides of (1) `4xy=4` To determine the x intercept

Y x 2 4x 5- To obtain the plot points manipulate the equation as below Given x2 y2 = r2 → x2 y2 = 4 Subtract x2 from both sides giving y2 = 4 −x2 Take the square root of both sides y = √4 − x2 Now write it as y = ± √4 −x2 '~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~Weekly Subscription $249 USD per week until cancelled Monthly Subscription $799 USD per month until cancelled Annual Subscription $3499 USD per year until cancelled
