Only numbers that are perfect squares have an odd number of positive factors. all other types of numbers have an even number. so if negative factors are included, then all numbers have an even number of factors.
Answer:
The equation is;
y = -2x - 3
Step-by-step explanation:
If two lines are parallel, then they have an equal value of slope
Mathematically we can generally have the equation of a line written as;
y = mx + c
where m
is slope and c is the y-intercept
In the case of the equation given, the slope of the line is -2
So technically, we want to get the equation of a line that has a slope of -2 and it passes through (2,-7)
The point-slope form can be written as;
y-y1 = m(x-x1)
So the equation we want to get is;
y-(-7) = -2(x-2)
y + 7 = -2x + 4
y = -2x + 4 - 7
y = -2x - 3
Answer:
no, y=3x+3
Step-by-step explanation:
plug both points into the equations:
- 9=4*2 +6 -> 9=8+6, doesn't work
- -6=4(-3)+6 -> -6=-6, works
one works but the other doesn't so now we find a line through both points
use the formula (y_2-y_1)/(x_2-x_1) to find the slope:
y=3x+b, plug in a point to find b:
