Question

Graph y=−83x+9.
Identify the x-intercept.

Answer 1

Answer:

x-intercept=-74

Step-by-step explanation:

for x-intercept (y=0)

y=83x+9

0=83x+9

-83x=-0+9

-83x=9

x=9/-83

x=-0.1

Answer 2

Answer:

x = -27/8

Step-by-step explanation:

y = $\frac{8}{3} x + 9$

to find x intercept let y = 0 then solve for x

0 = $\frac{8}{3} x + 9$

-9 = $\frac{8}{3} x$

divide both sides by 3

-9x3 = 8x

-27 = 8x

8x = -27

x = -27/8
