Question

write an equation in slope-inyercept form for the line with slope -4 that contains the points(0,-3)

Answer 1

Point-slope form: (y+3)=-4(x)
y=-4x-3

Answer 2

slope intercept form of a line is y = m.x + c where m is the slope and c is the intercept of the line.

now you know the slope (= -4). all you want to know is the intercept. Since point (0,-3) is in the line so the equation of line will satisfy for the given line

i.e, -3 = -4 (0) + c

=> c = -3

now we have both slope and intercept,

so the equation of line is y = -4x -3

give me medal, if i really helped you. :)
