Hello i need help on number 1,2,3,4,5 and 6.

A. m = -1

b = 1

Equation: y =-1x+1

B. m = 2

b = -3

Equation: y = 2x-3

Step-by-step explanation:

m = slope (rise/run)

b = y-intercept (where the line crosses the y-axis)

Line A:

Slope = -1

Y-intercept = 1

Equation: y = -1x+1

Line B:

Slope = 2/1

Y-intercept = -3

Equation: y = 2x-3

step-by-step explanation:

. your answer will contain x - and y -terms. (1 point) x ( ¿¿ 2 − 7 ) 2 +( y 2 − 9 ) 2 √ ¿ 12. what is the distance from the directrix (the crocodile river) to the point ( x , y )? write this equation. your answer will contain a y -term.
