Ответ:
A parallel line has the same slope as the original equation. Therefore, the slope (m in y=mx+b) will be 5. From there, we can use the point-slope formula and convert it into the slope-intercept formula (y=mx+b).
Point-slope is:
y-y₁=m(x-x₁)
Plug in our known values:
y-(-2)=5(x-(2))
Distribute and set it equal to y:
y+2=5x-10
y=5x-12

Ответ:
Step 1–find the common denominator (which is 8)
Step 2–multiply 3/4 times 2 which will give you 6/8
Step 3– Add 6/8 and 3/8 which will give you an improper fraction of 9/8
Step 4–Subtract 5/8 from 9/8
Therefore your answer is 4/8
