A line passes through the points (1, 3) and (2, 10). What is its equation in slope-intercept form?

Answer 1

y=mx + b where m=slope=7 = (10-3)/(2-1)

y=7x + b. plug in either point to solve for b= y intercept

3= 7+b

b =-4

y=7x-4 is the equation of the line through the two points, in slope intercept fomr

7 = slope, -4 or (0,-4) is the y intercept
