y = mx + b slope(m) = -4/3 ur y int is when x = 0....so it is 4 and in y = mx + b form, the slope is in the m position and the y int is in the b position so ur equation is : y = -4/3x + 4 <==
Fractions need common denominator to add or subtract them because without denominators a fraction is not a fraction, it is a whole number Example - 2/8 is a fraction but 2 is not a fraction
