Answer:
Question 1:
y = -3x + 5
Step-by-step explanation:
Question 1:
Slope(m) = -3
The line passes through point (1,2)
The slope(m) is given by change in y ÷ change in x
Take another point (x,y) on the line
-3 = [tex]\frac{y - 2}{x - 1}[/tex]
Cross multiplying gives;
y - 2 = -3x + 3
y = -3x + 5
NB: The other five questions are so easy if you just apply the formula.
