Question

Write the equation that describes the line in slope-intercept form. 25 points

Answer 1

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 = $\frac{y - 2}{x - 1}$

Cross multiplying gives;

y  - 2 = -3x + 3

y = -3x + 5

NB: The other five questions are so easy if you just apply the formula.
