1. find the value of y so that the line passing through (6, y) and (7, 5) has a slope of -3.

2. write the equation of a line in point-slope form that has a slope of -1 and passes through the point (-2, 5).

3.write the equation of a line in slope-intercept form passing through (2, 7) and (-2, 9) y=1/3x+5 and passes through (-9, 5)

5. write the equation of a line in slope intercept form that is perpendicular to the line y = –4x and passes through the point (2, 6)

6. write the equation of a line in slope-intercept form that has a slope of and passes through the point (8, -1)

What is the equation of this graphed line? enter your answer in slope-intercept form in the box.

Circle a has a diameter of 7 inches, a circumference of 21.98 inches, and an area of 38.465 square inches. the diameter of circle b is 6 inches, the circumference is 18.84 inches, and the area is 28.26 square inches. part a: using the formula for circumference, solve for the value of pi for each circle. (4 points) part b: use the formula for area and solve for the value of pi for each circle. (4 points)

Asystem of linear equations with more equations than unknowns is sometimes called an overdetermined system. can such a system be consistent? illustrate your answer with a specific system of three equations in two unknowns. choose the correct answer below. a. yes, overdetermined systems can be consistent. for example, the system of equations below is consistent because it has the solution nothing. (type an ordered pair.) x 1 equals 2 comma x 2 equals 4 comma x 1 plus x 2 equals 6 b. no, overdetermined systems cannot be consistent because there are fewer free variables than equations. for example, the system of equations below has no solution. x 1 equals 2 comma x 2 equals 4 comma x 1 plus x 2 equals 12 c. yes, overdetermined systems can be consistent. for example, the system of equations below is consistent because it has the solution nothing. (type an ordered pair.) x 1 equals 2 comma x 2 equals 4 comma x 1 plus x 2 equals 8 d. no, overdetermined systems cannot be consistent because there are no free variables. for example, the system of equations below has no solution. x 1 equals 2 comma x 2 equals 4 comma x 1 plus x 2 equals 24
