Question

Find the equation of the line that passes through the points (-4,3) and (10,5). Plug in your slope and y-intercept, or your values for a and b into the equation below (if your answers are not whole numbers leave them as fractions!).

y =_____x+______

Answer 1

y = 1/7x + 25/7

Explanation:

Find the slope using the formula [ y2-y1/x2-x1 ]

5-3/10-(-4)

2/14

1/7

Find the y-intercept using slope-intercept form [ y = mx + b ], the slope, and one of the points given.

y = 1/7x + b

3 = 1/7(-4) + b

3 = -4/7 + b

3 4/7 = b

Put everything we solved for back into the formula.

y = 1/7x + 25/7

Best of Luck!
