Answer:

y = 4x - 19

You should also try solving it yourself to make sure I did not make any mistake.

Step-by-step explanation:

We already know the slope so, so far the equation should look like this.

y = 4x + b

Now we just need to insert the point into the equation. So point (7,9) 7 should replace the x and 9 will replace the y. It will look like this:

9 = 4 \times 7 + b

when you solve this equation you'll get b

b =  - 19

So the equation is

y = 4x - 19

If mark got 6 questions out of 40 incorrect what percent of the questions did he get correct?
kap26 [50]
So if 6 out of 40 are incorrect, 40-6= 36 must be correct.
In order to gain percentage you do proportions.
36/40 = x/100.
Multiply 36 times 100 then divide by 40, which is 90.
The answer is 90%.
90% of the questions he got were correct.
