A line passing through the point (7, 6) has a slope of 2.
Masja [62]
An equation in point-slope form is
y - y1 = m (x - x1)

Your point is (7,6) and your slope is 2
y1 is the y coordinate of your point (in this case 6)
x1 is the x coordinate of your point (in this case 7)
m is your slope (in this case 2)

Now you just have to plug these numbers in:
y - 6 = 2 (x - 7)

A store is having a sale on jelly beans and trail mix. For 3 pounds of jelly beans and 2 pounds of trail mix, the total cost is
klasskru [66]
3j+2t=14  subtract 2t from both sides

3j=14-2t  divide both sides by 3

j=(14-2t)/3

...

5j+6t=28, using j found above in this equation yields.

5(14-2t)/3+6t=28  perform indicated multiplication on left side

(70-10t+18t)/3=28  multiply both sides by 3

70-10t+18t=84  combine like terms on the left side

70+8t=84  subtract 70 from both sides

8t=14 divide both sides by 8

t=$1.75, and since j=(14-2t)/3

j=(14-2(1.75))/3

j=$3.50

So a pound of trail mix costs $1.75 and a pound of jelly beans costs $3.50.
