Question

find the solutions to the system.
y = x^2 - 3x - 1
y=8x - 1
a. (0,-1) and (11,388)
b. (0,01) and (11,87)
c. (-1,0) and (87,11)
d. no solutions

Answer 1

replace x and y with the coordinates given and see which ones work

Answer 2

plug in \(y=8x-1\) into \(y\) and solve for \[8x-1=x^2-3x-1\]

Answer 3

So you move the function on the LHS to the right and set it = 0. \[0=x^2+x(-3-8)-1+1\]

Answer 4

is it a ? @Jhannybean
