I’m not very good at explaining but if we explain from the beginning the equation is y=m(x)+b and m means the slope while b means y- intercept so all you have to do is substitute these variables with the numbers in the problem basically it would be y=10x+10 also the picture attached is how you graph it. Hope this helped:)

there is a certain number. If you add 30 7 to it, then subtract 22 7 from the previous result, and then subtract that difference from 59/7, after that you will get 19 7. What is a certain number?

Answers

Step-by-step explanation:

59 / 7 - ( x + 30 / 7 - 22 / 7 ) = 19 / 7

59 / 7 - ( x + 8 / 7 ) = 19 / 7

59 / 7 - x - 8 / 7 = 19 / 7

- x = 19 / 7 - 59 / 7 + 8 / 7

- x = - 32 / 7

x = 32 / 7
