What is the value for f(x) = 4^2 - 100 when x= 2

F (2)= 4^2 -100
2 f = 16 + -100
2 f =(16 + -100) (combine like terms)
2 f = -84
2 f/2 = -84/2 (divide both sides by 2)
f = -42

Abit confused about what you mean, but i think you might be referring to slope intercept form: y = mx + bin that case b, or the y intercept is already given.(0,-1)find the slope by using the formulay2 - y1/x2 - x1the final slope will be 4/2, equivalent to 2.now your equation should look like thisy = 4/2x -1sorry if this didn’t you out!

Sorry i meant b in the other question
