Answer:
y = -1/5x + 49/5
Step-by-step explanation:
first rewrite the equation so the y is lone
2x + 10y = 7 becomes y = -1/5x + 7/10
If two equations are parallel, that means their slopes are the same.
So the new equation should also have -1/5 as slope.
The equation is now y = -1/5x + b
b is the y-intercept. To find b, let's substitute the given coordinate.
y = -1/5x + b
9 = -1/5(4) + b
9 = -4/5 + b
b = 49/5 or 9 4/5
So equation is y = -1/5x + 49/5
Answer:
7/10
Step-by-step explanation:
i put it into y=mx+b for to find it, lots of opposite operations
