Y - 4x = 7...y = 4x + 7
now sub 4x + 7 in for y in the other equation
2y + 4x = 2
2(4x + 7) + 4x = 2
8x + 14 + 4x = 2
12x = 2 - 14
12x = - 12
x = -1
y - 4x = 7
y - 4(-1) = 7
y + 4 = 7
y = 7 - 4
y = 3
solution is : (-1,3)
since 1.5 is half of 3.0 all ouj havr t o do is multiply by 2 2.4*2=4.8 answer

.
Answer:
1
Step-by-step explanation:
1. To get the slope, you need to divide the rise by the run.
2. Pick two points each on the X-axis and pick corresponding points on the Y axis and then name them y2, x2 and y1, x1.
3. The rise will be y2-y1
4. The run will be x2-x1
5. Therefore, the slope is rise/run = (y2-y1)/(x2-x1)
In this case, let's take 2 on the X axis as x2 and the corresponding point on the Y axis as y2 which in this case happens to also be 2.
Now, let's take 1 on the X axis as x1 and the corresponding point on the Y axis as y1 which is also 1.
now using the formula (y2-y1)/(x2-x1), we get: slope = (2-1)/(2-1) = 1
