Y=-1.5x+1.5
we can see the y-intercept is at (0, 1.5).
And when the line goes to the right 1 unit, it's at (1, 0), which is going down 1.5 units, meaning the slope is -1.5x. you can check this in desmos graphic calculator and you'll see the points on the line if you want
One for 5.8 and one for 1.2

Answer:
7√6 - 5√7
Step-by-step explanation:
5√7 + 12√6 - 10√7 - 5√6 (rearranging)
= (5√7 - 10√7) + (12√6 - 5√6) (factor out √6 and √7 respectively)
= (5 - 10) √7 + (12 - 5)√6
= -5√7 + 7√6 (rearrange)
= 7√6 - 5√7
