A fraction is a short way to write a division problem.
Whenever you see a fraction, it means
(the top number) divided by (the bottom number).
When you pick up your pencil or your calculator and actually do the
division, the answer to the division is the decimal form of the fraction.
To change that fraction 1/5 to a decimal, divide 1 by 5 .
Then, to change the decimal to a percent, move the
decimal point 2 places that way ==>.

The question says to identify an equation in point-intercept form for the line that's parallel to y = -3x + 7 that passes through (2, -4).
If you need to find an equation in point-intercept form that passes through a point, you will substitute the coordinate in this formula:
-> y - yo = m (x - xo)
Where:
(2, -4) -> xo = 2 ; yo = -4
m = Slope
You don't have the slope, but you have the information that the line is parallel to y = -3x + 7. Then you need to know that to a line be parallel to another the Slopes of each other must be equal, mr = ms.
Let's find the slope of the equation given, it is in a slope-intercept form, so:
y = mx + b
R: y = -3x + 7 // I will call this one R line, and the other S.
mr = -3
If the mr = ms, and mr = -3, then the ms = -3 too.
S: y - yo = ms (x - xo) // (2, -4) & ms = -3
-> y - (-4) = -3 (x - 2)
-> S: y + 4 = -3 (x - 2) -> This is the point-slope form.
-> y = -3x + 6 - 4
-> S: y = -3x - 2 -> This is the slope-intercept form.
I didn't understand what is the point-intercept form that the question requests, but by logic, i think that's the point-slope form.
Answer: The equation in point-intercept form is: y + 4 = -3 (x - 2).

Side lengths: RS=7 and ST=7, and angle=90 degrees
Why?
Since second coordinates of R and S are the same so we can just count the length by adding first coordinate of R and first coordinate of S= |-3|+4=7
Since first coordinates of R is the same as first coordinate of T so we can just count the length by adding second coordinates of S and T=5+|-2|=7
Angle: RST is =90 degrees because triangle RST is right angled triangle. Why? Because RS is parallel to X axis(the same second coordinates of R and S) and ST is parallel to Y axis(the same coordinates of S and T) .
