Aline includes the points (0, 4) and (1, 7). what is its equation in slope-intercept form?

I believe it’s m=3 b=4 I don’t understand really so I think this is my answer

1)the  equation in slope- intercept is y-y1 = m(x-x1) , but in first place you  must determine the slope with the points given and the formula m = y2-y1/x2-x1,

2) x1 = 0, y1 = 4 ;  x2= 1, y2= 7,  m = 7-4/ 1-0 , m = 3/1 = 3

3)  now wit a point and its slope determine the equation y-4 = 3(x-o)
