Simplify. 4*3 · 4*4
4*9

a) 4*16

b) 4*2

c) 1/4*2

d) 1/4

A)4*16

because 4*3•4*4•4*9
you have to add the exponents

3+4+9=16
keep the number

so 4*16 is the answer

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!
