I don’t remember how to do a and b but A is 39
Y = -3x + 4
In y = mx + b form, the y intercept will be in the b position.
y = mx + b
y = -3x + 4......so ur y intercept is 4.....or (0,4)
just so u know....in y = mx + b form, the slope will be in the m position....so ur slope would be -3
if you are multiplying by 5, then the blue needs to be 25 quarts and the yellow needs to be 15 quarts not 9. If you are multiplying by 3 then it would be 9 quarts yellow and 15 quarts blue. hope this helps :)
