Question

]Identify the correct x intercept and y intercept of the equation x + 7y = -21.

x intercept = (3, 0); y intercept = (0, 21)

x intercept = (-3, 0); y intercept = (0, -21)

x intercept = (21, 0); y intercept = (0, 3)

x intercept = (-21, 0); y intercept = (0, -3)

Answer 1

solve for y first so put it in y=mx+b form
b is the y-int and to find x int set y=0 and solve for x

Answer 2

sohow do i dothat

Answer 3

to solve for y subtract x on both sides and then divide both sides by 7

Answer 4

so what u do is convert it into a mx+b equation which will be as follows;-
\[y=\frac{ -1 }{ 7 }x-3\]
and then u make y=0 to find the x intercept and x=0 to find the y intercept

Answer 5

so that means that your x intercept according to me should be (-21,0) and the y intercept should be (-3,0)

Answer 6

thankz
