First put it into slope intercept form. which is y=mx+b, in other words solve for y and get y by itself.
4x + 5y = -3
5y = -4x -3
y = -4/5x -3/5
The slope of any line in slope intercept form is the m, or the coefficient to x.
In this line the slope will be -4/5.
Now we find the slope of a line parallel to this line. Parallel lines have the same slope,
So the slope of a line parallel to 4x +5y = -3 is -4/5
Explanation:
This is the probability = 1 ÷ 6 = 0.167
or 16.7 percent chance.
Answer:
c. ½x + 4 = 12; x = 16
Step-by-step explanation:
1/2 x ( Half of the allowance spent at movies & x is allowance )
1/2x + 4 ( Earned additional $4 )
1/2x + 4 = 12 ( Had $12 at the end of the week )
Check:
1/2 16 +4 = 12
8 + 4 = 12
12 = 12
Correct!
Answer:
2x + 4y = 16.
Step-by-step explanation:
14x - 7y = 8
Convert to slope-intercept form:
-7y = -14x + 8
y = 2x - 8/7
The slope is 2 so the line perpendicular to it has a slope of -1/2, so we have:
y = 1/2x + c
This line passes through the point (-2, 5) so:
5 = -1/2* (-2) + c
5 = 1 + c
c = 5 - 1 = 4
So our equation is y = -1/2x + 4.
Convert to standard from
4y = -2x + 16
2x + 4y = 16.
