Question

how do i get a slope-intercept?

Answer 1

From... co-ordinates? Slope:\[\Large \frac{{\Delta y}}{{\Delta x}} = \frac{{{y_2} - {y_1}}}{{{x_2} - {x_1}}}\]
And the intercept is where x = 0.

Answer 2

slope-intercept form is:
y = mx + b, where m is the slope shown above ^^

Answer 3

(3,-12) and (-4,2) are the co-ordinates can any one show how to work this problem?

Answer 4

first find the slope using formula above

Answer 5

slope=14/-7

Answer 6

good, reduce 14/-7 = -2

then pick a point and use the x and y values to solve for b (y-intercept)
y = mx +b (m=slope =-2)
y = -2x +b

Answer 7

y=-2+(-6)

Answer 8

yes, so that is the line that goes through those 2 points

Answer 9

thanks
