Hello, Trinity,
The question is asking for the details of an equation of the form y = mx + b, where m is the slope.
The slope is defined as "-3 over 4," which I interpret as -(3/4)
Replace m in the equation with the actual slope: y = -(3/4)x + b
We also know the line passes through point (0.2, -8), which are the x and y coordinates of that point. We don't know b yet, so let's substitute these values which we know satisfy the equation (the line passes through that point):
-8 = -0.75*(0.2) + b,
-8 = -0.15 + b
b = -7.85. Therefore,
y = -0.75x - 7.85
