Answer: (y-2)=3(x-1)
Step-by-step explanation:
1. The first thing you'll need to do is to find the slope of the line passing through (1,2) and (2,5). To find the slope of the line, use this formula: y2-y1/x2-x1and subsitute in the values
5-2/2-1= 3/1 =3
The slope(m) is 3, so that cuts down to two options. All you need to do now is to put in in slope- intercept form by using this:
(y-y1)=m(x-x1) <--- subsitute in values
(y-2)=3(x-1)
