In slope-intercept form, we can classify the following values.
m = slope
b = y-intercept
Turn the equation into slope-intercept form (y = mx + b).
3y + 2x = -21
~Subtract 2x to both sides
3y + 2x - 2x = -21 - 2x
~Simplify
3y = -21 - 2x
~Divide 3 to both sides
3y/3 = -21/3 - 2/3x
~Simplify
y = -7 - 2/3x
~Put into correct order
y = -2/3x - 7
So, the y-intercept is -7
Best of Luck!
Every x value is multiplied by 3, expanding the graph

Photo-math take a picture of your problem and it will give you your answer
8/15 = 56/105
This may be solved using proportion.
a/b = c/d
ad = bc where cross products are equal.
a = 8
b = f
c = 56
d = 105
ad = bc
8*105 = f*56
840 = 56f
840/56 = 56f/56
f = 15
56 ÷ 7 = 8
105 ÷ 7 = 15
