Answer:
Step-by-step explanation:
the standard form is : ax+by = c
this line passes through (7,-3) : when x=7 and y = -3 means : 7a-3b = c
has a y-intercept of 2 : when x= 0 and y =2 means : 2b = c
you have the system : 7a-3b = c ....(1)
2b = c........(2)
let : c =2
so b = 1 7a - 3 = 2
7a =5 a = 5/7
5/7 x + y = 2
5x +7y =14........an equation in standard form
