To calculate how many points this person got, take 90% of the total:
0.9(70) = 63
A test score of 90% is 63 points out of 70.
To get from −8 − 8 to the answer you really want, just take the absolute value! That is, to find the distance between<span> any </span>two<span> real numbers: subtract them in any order</span>
Answer:
y = 4x - 7
Step-by-step explanation:
Given the following data;
Points (x, y) = (4, 9)
Slope, m = 4
To write the equation in point-slope form;
The equation of straight line is y = mx + c
Where;
m is the slope.
x and y are the points
c is the intercept.
First of all, we would find the intercept c;
9 = 4*4 + c
9 = 16 + c
c = 9 - 16
c = -7
Next, we write the equation in point-slope form;
m = 4 and c = -7
y = 4x - 7
