Identify the equation of the line having a slope of -3 and a y- intercept of 7 A y + -3x +12
b y = 3x - 7
c y = 3 + 7
d y = -3x + 7

D.

Step-by-step explanation:

We can use the slope-intercept form:

Where m is the slope and b is the y-intercept.

We know that the slope is -3.

And the y-intercept is 7.

Hence, we will substitute -3 for m and 7 for b. This yields:

Therefore, our answer is D.

C)

Step-by-step explanation:

6^2 + 3^2 = 45, and the   is roughly 6.7

also equals roughly 6.7, so is the answer
