What is the y-intercept ofa line that has a slope of -3 and passes through (0,-7)

y = - 7

Step-by-step explanation:

The y- intercept is the point on the y- axis that the line passes through.

The line passes through the y- axis at (0, - 7), hence

the y- intercept is - 7

Slope-intercept form: y = mx + b   [m is the slope, b is the y-intercept or the y value when x = 0 ---> (0 , y)]

Since you know m = -3, you can plug that into the equation

y = mx + b

y = -3x + b       To find b, plug in the point they gave you into x and y, but since x = 0, your y-intercept is -7

10/60

step-by-step explanation:

if you divide 10 by 60 the answer is 0.166666 while if you divide or solve the other problems it equals 0.6
