3 is the slope

Step-by-step explanation:

Since you know the slope formula is "y=mx+b" where m is the slope and b is the y-intercept, you can rearrange the equation there to match the slope formula. When rearranged it comes out to "-4y=-12x+3" and then when simplified (divide both sides by -4) the equation comes out to "y=3x-3/4". As stated before the "m" is the slope and the m here is 3, therefore 3 is the slope in this problem.

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1

y > 1/3x

y < = -x + 4

hope this : )
