36:20, or 36/20. To simplify, find a number both 36 and 20 can be divided by. 36: 1, 2, 3, 4, 6, 9, 12, 36 20: 1, 2, 4, 5, 10, 20 The largest number both have in common is 4. So, divide both 36 and 20 by 4 so that you have: 9:5
(For 3) For every time a person gets a touchdown, x represents that
for every time a person person scored a successful extra-point attempt, y represents that.
And they team scores 63, so....
the equation would look like this
63=3x+7y
(For 4) You find the y-intercept by turning the standard form equatio into the slop intercept form
(Helper's note, multiplying by its reciprocal is the same as dividing it by a whole number, in the case dividing the number by 7 is the save as multiplying the number by )
Then plugging x=0 and solve for y, which in this case, y=9
(For the graphing) Turn 63=3x+7y into a slope intercept form, which is and graph from there
