Answer:
The equation for a line is written as Y - Y1 = slope(x-X1)
You are given (1,-2) as a point, so x1 = 1 and y1 = -2 and the slope is given as 3/4
replace those values in the equation:
y - (-2) = 3/4(x-1)
When you have a minus and a negative number as above it becomes an addition.
The equation becomes:
y+2 = 3/4(x-1)
