SOLUTION: Given a line containing the points (1,4), (2,7), and (3,10) determine the slope-intercept form of the equation, provide one additional point on this line, and graph the function.

Question 68022: Given a line containing the points (1,4), (2,7), and (3,10) determine the slope-intercept form of the equation, provide one additional point on this line, and graph the function.

(1,4)(2,7),(3/100 IS A LINE WITH A SLOPE OF ---
(10-4)/3-1)
6/2=3 FOR THE SLOPE.
NOW REPLACE THE X & Y UNKNOWNS & THE SLOPE (m)IN THE FORMULA Y=mX+b & FIND THE Y INTERCEPT.
4=3*1+b
4=3+b
b=4-3
Y=1
THEREFORE THE FORMULA IS
Y=3X+1
(graph 300x200 pixels, x from -3 to 4, y from -5 to 5, Y = 3X +1).
