Answer:
Step-by-step explanation:
Remark
You can use the two points marked to find the slope. One of them is the y intercept which you need to get the equation.
(0,4) is one of the points. This is the y intercept.
(8,0) is the other point you can use
Slope
m = (y2 - y1)/(x2 - x1)
Givens
y2 = 4
y1 = 0
x2 = 0
x1 = 8
Solution
m = (4 - 0) / (0 - 8)
m = 4/-8
m = - 1/2
y_intercept = 4
Equation
y = -1/2 x + 4
Answer:
y = (-3/5)x - 7
Step-by-step explanation:
you are given the points (5,-10), (-10,-1)
a slope of (-1+10)/(-10-5) = -9/15 = -3/5 can be determined
using the point (0,-7), we can get y+7=(-3/5)(x - 0)
simplified: y = (-3/5)x - 7
54 because there are 12 inches in a foot 12 divided by 3 is 4 and 6 divided by 3 is 2. Add the 2 and 4 and multiply that by 9
4.8y - 6.9 = 3.18
4.8y= 3.18 + 6.9 (I added 6.9 to both sides)
4.8 y = 10.08 (I added 3.18 by 6.9)
y = 2.1 (I divided 4.8)
Hope this helps!!
