The formula would be: <span>y = mx + b </span><span> Now, let's look at the information we know. m = slope b = y-intercept y-intercept = -6 x-intercept = -2 </span> First, we would need to determine the slope. The formula for slope is m =
Plug your coordinates in and solve it. = 6/-2 = -3
Now, since we have the slope and y-intercept, we are ready to plug them into the formula. y = -3x - 6
You can easily find the slope of the line from these 2 intercepts / points. 0-[-6] m = rise/run = ------------ = 6/2 = 3 = m -2-0 Now stick values into the point-slope formula as follows:
y-(-6) = 3(x-0), or y + 6 = 3x, or y = 3x - 6 (answer)
