Find the equation of the linear function represented by the table below in slopeintercept form.
x y 1 5 2 8 3 11 4 14
I got this!
Use any two points to find the slope. (1,5) and (2,8) 8  (5) ————— = slope {subtracted ycoordinates over subtraction of xcoordinates......”rise over run”} 2  1 3/1 = slope {subtracted in numerator and denominator} slope = 3 Use the slope and any point, and substitute into slopeintercept form, to find the yintercept. y = mx + b {slopeintercept form} m is the slope and b is the yintercept (1,5) is a point and 3 is the slope y = mx + b {slopeintercept form} 5 = 3(1) + b {substituted 5 for y, 3 for m, and 1 for x} 5 = 3 + b {multiplied 3 by 1} b = 2 {added 3 to each side} yintercept = 2 slope is 3 and yintercept is 2 Substitute into slopeintercept form. y = 3x  2 is the equation of the line Ask the House
