The second one seems about right.
4¹/₃x = ⁵/₁₂x - 6
3¹¹/₁₂x = -6
x = -1²⁵/₄₇
480. 8 x 60 would equal 480
equation in slope-intercept form is:

Step-by-step explanation:
The general form of slope-intercept form is:

where m is the slope and b is the y-intercept
In the question we are given slope m=9 and a point(0,7)
We will find b i.e y-intercept

So, value of b=7 and value of slope m=9
So, equation in slope-intercept form is:
