Write an equation of the line that passes through (1, 2) and is perpendicular to the line y=13x+4.

y = -1/13x + 27/13

Step-by-step explanation:

A perpendicular line will have the opposite reciprocal and sign.

So the perpendicular line slope to y = 13x + 4 would be -1/13

NOW PLUG IN (1, 2) TO GET THE Y- INTERCEPT

2 = -1/13(1) + b (b represents the y- intercept)

2 = -1/13 + b (add 1/13 to both sides)

y = -1/13x + 27/13 is the perpendicular line.

Hope this helps ya!!

you never say the total so we cant find the percentage used for petrol

step-by-step explanation:

b. b < 1 might be the correct answer
