What is the y-intercept of a line that has a slope of negative 3 and passes through point 0 and -7

The y-intercept of a line that has a slope of negative 3 and passes through point 0 and -7 is

Solution:

Let us assume that the slope is m and the y intercept of the line is b

Hence, --------- (i)

y intercept means we need to find the value of y when x is 0

Here the line passes through point (0,-7) and slope m = (-3)

Now putting the point (0,-7) in equation (i) we get,

Anything multiplied by 0 is 0,

So, the line will be

here is your mark brainliest

a=24; b=12

step-by-step explanation:

a/b=2: 1

a=2b

36/(1+2)=12

b=12

a=24
