Find the standard form equation of a line that goes thru -6

Question

(1) Use m = (y₂ -y₁)/x₂-x₁ to find the slope of a line that goes thru (-2, -5) and (3, -2).

(2) Find the slope of the graph on the right: (careful, be sure you choose values that are integers)

(3) Find the point-slope form equation of a line that goes thru (3, 8) and is parallel to y = -2/3 + 3.

(4) Graph x = - 4, then give the slope of the line.

(5) Find the slope-intercept form equation of a line that goes thru the points (-2, -5) and (3, -2).

(6) Rewrite 2x + 4y = 10 into slope-intercept form, then state the slope and the x- and y-intercepts.

(7) The graph on the right shows the relationship between the length of a person's femur and the height of that person.

(a) What is the length of the femur if a person is 70 inches tall?

(b) If someone's femur is 2.3 inches long, how tall would you expect them to be?
