Plz help asap cant figur out
sesenic [268]

Answer:

a) y=3x-11

b) y=-1/3x-1

Step-by-step explanation:

First find the slope of the line

rise/run

rise is 3

run is 1

so slope is 3

since this line is parallel to "a", the slope of "a" will also be 3

the equation of a will be

y-y1=3(x-x1) -- where x1 and y1 will be the points it passes through (3,-2)

y-(-2)=3(x-3)

y+2=3x-9

y=3x-9-2

y=3x-11

since this line is perpendicular to "b", the slope of "b" will also be reciprocal negative , -1/3

y-y1=-1/3(x-x1) -- where x1 and y1 will be the points it passes through (3,-2)

y-(-2)=-1/3(x-3)

y+2=-1/3x+1

y=-1/3x+1-2

y=-1/3x-1

Graph a line Slope of -5 and contains the point -3,-4
Papessa [141]

Answer:

y = -5x - 19

Step-by-step explanation:

Find the y intercept using slope intercept form [ y = mx + b ]

y = -5x + b

-4 = -5(-3) + b

-4 = 15 + b

-19 = b

y = -5x - 19

Best of Luck!
