Ronch [10]

The formula for point slope is:

y-y1=m(x-x1)

m is your slope: 3; plug in 4 for y1 and 2 for x1

y - 4=3(x-2)

Can some answer these math questions asap thanks
Alexus [3.1K]

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

(-3x)63=3x+7y (-3x)\\(\frac{1}{7}) 7y=(-3x+63)(\frac{1}{7} )\\y=-\frac{3x}{7} +9

(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 \frac{1}{7})

Then plugging x=0 and solve for y, which in this case, y=9

y=\frac{-3(0)}{7} +9\\y=9

(For the graphing) Turn 63=3x+7y into a slope intercept form, which is y=-\frac{3x}{7} +9 and graph from there
