Quadrent 1 because they are both positive numbers
The answer is 10mm, I answered this in a previous question.
To get the decimal you have to divide the numerator by the denominator.
-19÷-50=-0.38
-19/50=-0.38
Linear functions can be written in the form y=mx+b, where:
y is a y coordinate on the line
m is the slope of the line
x is the x coordinate on the line that corresponds with the y coordinate in the equation
b is the y-intercept of the line
So for the equation y=-10x+1:
m=-10 and b=1 so the slope of the line is -10, and the y-intercept is 1. Your answer is B.
