Answer:
y = -3x + 2
Step-by-step explanation:
The linear equation is in the form
y = mx + b
where m is the slope and b is the y-intercept
the slope can be calculated using two points
Let us have; (-2,8) and (0,2)
The equation of the slope is ;
m = (y2-y1)/(x2-x1) = (2-8)/(0+2) = -6/2 = -3
So for the y-intercept, we select any of the points to substitute
Let us have (0,2)
Substitute this into;
y = -3x + b
2 = -3(0) + b
b = 2
So the equation is;
y = -3x + 2
Answer: C:10
Step-by-step explanation:
Equation of a line passes through (a,b) and (c,d) :

Equation of line passes through A(-2,8) and B(4,14) will be :


For y-intercept , put x= 0 , we get y= 10
So, the y-intercept = 10
Thus , correct option = C:10
Answer:
y = -2x - 2
Step-by-step explanation:
Given:
m = -2
Slope-intercept:
y - y1 = m(x - x1)
y + 8 = -2(x - 3)
y + 8 = -2x + 6
y = -2x - 2
