Answer:
3.) 63=3x+7y
4.) Y-intercept is 9
Step-by-step explanation:
(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
You would have to put 21.3 on top and 1.9 under it. then you would have to borrow the number. the answer would be 19.4
