Answer:
y= -9x+14
Step-by-step explanation:
the equation of a straight line is y=mx+c
m is the slope
And we are given a y and x term
So we substitute these into the equation:
5= -9(1) + c
rearragne to find c
14= c
so the full equation is:
y= -9x+14
Answer:
D
Step-by-step explanation:
The y-intercept must be at -7, so that eliminates C.
Because of the direction of the line, the slope needs to be negative. This eliminates B.
The slope of the line is -7/6, so D is the correct answer.
I have a photo that shows how I got the answer and what the answer is (Key: Red represents my work, while highlighter shows what the answer is):
For question 2 it is 15
Because: 4 time 6 is 24 and then you minus 9 which is 15
So there you have it the answer is 15
