Answer:
y = 7x - 9
Step-by-step explanation:
y = mx+b
m = slope = 7
b = y-intercept = -9
Y = mx + b
slope(m) = 3/4
(-8,7)...x = -8 and y = 7
now we sub and solve for b, the y int
7 = 3/4(-8) + b
7 = - 6 + b
7 + 6 = b
13 = b
so ur line is : y = 3/4x + 13

Answer: y=5x+7
Step-by-step explanation:
Since we are given the slope, all we have to do is plug in the given point and solve for the y-intercept.
-3=5(-2)+b [multiply]
-3=-10+b [add both sides by 10]
b=7
Now, we know the equation is y=5x+7.
Answer:
See below
Step-by-step explanation:
Perpendicular lines have slopes which are negative reciprocals. Line a with the equation y = 13x + 3 has slope 13. This means Line b which is perpendicular will have slope -1/13.
The equation of line b is any equation where -1/13 is the slope/
Example: y = -1/13x + 5 or y = -1/13x - 6
