What equation represents the line that has a slope of -4 and passes through the point (1, -2)

The equation that has a slope of -4 and passes through the point (1,-2) would be: y=-4x+2

since y=mx+b,
m=-4
and you know one point that the line passes through-->y=-2, x=1
you can use m, y and x to find the b (the y-intercept)
y=mx+b
(-2)=(-4)(1)+b
2=b

So if you put together the slope that is given, and the y-intercept that you found using the point: y=(-4)x+2

Y = -4x + 6

that is the awnser the the question you asked today

Technically speaking, histograms are another version of bar charts, if you need to work one out then skim through google hope-o that -o!
