A is the correct answer. ☺️
Answer: y=-3x+29
Step-by-step explanation:
First put in y-intercept form to find the slope

Slope of the 1st equation is 1/3- the slope of the line perpendicular is the opposite reciprocal, so in the case it is -3
Use the point and the new slope to write the new equation in point slope format

Answer:
y=7x + 5
Step-by-step explanation:
sub into y= mx + c
where m = slope/gradient (7)
and c = y-value of y-intercept (5)
Answer:
If y = x then when x = -1 then y = -1
