WITCHER [35]

The point-slope form of a line:

y-y_0=m(x-x_0)

We have:

m=\dfrac{2}{5}\\\\(-4,\ -7)\to x_0=-4,\ y_0=-7

Substitute:

y-(-7)=\dfrac{2}{5}(x-(-4))\\\\y+7=\dfrac{2}{5}(x+4)

Help me please I’ll donate money
Virty [35]

12. It's similar to having an infinite number of solutions because there isn't a specific solution to answer the question.

13. For the equation 0.9x + 5.1x - 7 = 2(2.5x-3), there is only one solution and it is x=1

14. The error that your friend made was that she added extra 16x to the equation. the correct answer is that there is no solution.

16. the equation  6 (x+2)= 5 (x+7) has only one solution. it is x=3.

sorry i wasn't able to answer the other 3,

by the way you don't need to send money, because we are here to help
