algebra 2
The answer is y=2x+7. First put it in point slope form then solve it into slope-intercept form. Use the same slope because having parallel lines means the same slope.

biology
A dominant gene A produces wire-haired texture in dogs. Its recessive aamllele a produced smooth hair. Cross the heterozygous wire-haired dog with homozygous smooth-haired dog. List the genotype and phenotype ratios of all the possible offspring.

Geometry
the answer to this queston is acute! :)

physics
A small cart weighs 15.0 N.  If a constant force of 25 N is  used to move the cart horizontally across the desk, A]  What will be the acceleration of the cart? B]How far will the car move in 1.0 second

Issac has to do 1000J of work on a 5kg box, and all the work he did simply went into lifting it above the ground. How high above the ground will the box be when all the work has been done?

physics
a football punter accelerates from rest to a speed of 8 m/s during the time in which his toe is in contact with the ball (about 0.21 s). If the football has a mass of 0.50 kg, what average force does the punter exert on the ball?

physics
a bag of sugar weighs 5.00 lb on earth. What would it weigh in newton on the moon, where the free fall is one-sixth that of the earth?

physics
a 8.0 kg object undergoes an acceleration of 2.2 m/s squared.what is the resulting force acting on it?

physics
a football punter accelerates a football from rest to a speed of 7 m/s during the time in which his toe is in contact with the ball (about 0.18 s). If the football has a mass of 0.50 kg, what average force does the punter exert on the ball?

physics
While exploring a cave, a spelunker starts at the entrance and moves the following distances: 75.0 m north, 225 m east, 160 m at an angle 30.0° north of east, and 150 m south. Find the resultant displacement from the cave entrance.
