this is the process of doing it. hope you like it
Y=5/2x+5 because the slope is 5/2 and the y-intercept is 5
Step-by-step explanation:
let the unknown number be x
1St step: twice the number is 2(x) =2x
2nd step: 2x -14
3rd step: 2x - 14=28...
It would be the first graph because it lands on -1 and +4
Step-by-step explanation:
making x subject in eq 1
x= (-1-9y)/-14
substituting the value of x in eq 2
17(-1-9y/-14)=7+9y
(-17-153y)/-14=7+9y
-17-153y=-98-126y
-17+98=153y-126y
81=27y
y=3
substituting this value of y in eq 1
-14x=-1-9(3)
-14x=-28
x=2
(x,y) = (2,3)
