Write the slope-intercept form of the equation with the given characteristics.
1. Slope = 3/2, y - intercept is at (0,-4)
Use the equation y = mx + b where m is the slope and b is the y-intercept.
Given: m = 3/2 and b = -4
Hence the equation of the line is highlight%28y+=+%283%2F2%29x+-+4%29
2. Passes through (3,-1) and (4,-6)
First, compute the slope.
The slope is equal to "change in y" divided by "change in x"
slope, m = %28%28-6%29+-+%28-1%29%29%2F%284-3%29+=+-5
Next, we use the point-slope form y+-+y%5B1%5D+=+m%28x+-+x%5B1%5D%29
We choose (x%5B1%5D, y%5B1%5D) = (3, -1)
y - (-1) = -5(x - 3)
y + 1 = -5x + 15
highlight%28y+=+-5x+%2B+14%29 is the equation of the line

3. Parallel to the line y = -4x + 2, and passes through (1,-3)
Use the fact that parallel lines have equal slopes.
y+-+y%5B1%5D+=+m%28x+-+x%5B1%5D%29
y - (-3) = -4(x - 1)
y + 3 = -4x + 4
highlight%28y+=+-4x+%2B+1%29
