Step-by-step explanation:
the true answer is (A)
the right side : 9^4 / 9^1 = 9^3
the left side : 9^8 / 9^5 = 9^3
two side are equal
Turn it into y=mx+b form so it is y=2x+2 the b=2 so y intercept is (0,2) and the slope is 2, do a rise of two and a run of 1 and then connect the dots
10 - 2x = -30
-2x = -40
2x = 40
x = 20
Plug any number in for x and find the resulting y, then if you need to graph place the coordinate points on the plane. For example if you set x=2 the equation becomes y=0.5(2). From here we can see 0.5(2)=1 and this is equal to 1 so in a data chart you would write under x the number 1 and under y the number 2.
