y = -3/25x +1 59/100y=325x+159100

m = -3/25 and c = 1.59m=325andc=1.59

Explanation:

Lets find the slope first: m = (y_2-y_1)/(x_2-x_1)m=y2y1x2x1

rarr" " m = (7/4-3/2)/(-4/3-3/4) m=74324334

m= ((7-6)/4)/((-16-9)/12) = (1/4)/((-25)/12)m=76416912=142512

m = (1xxcancel12^3)/(cancel4xx-25) = -3/25

Substitute m and one point into y-y_1 =m(x-x_1)

m = -3/25 " and the point, " (3/4, 3/2)

y-3/2 = -3/25(x-3/4)

y = -3/25x+9/100+3/2

y = -3/25x +1 59/100
