Step-by-step explanation:
The slope-intercept form of an equation of a line:
<em>m</em><em> - slope</em>
<em>b</em><em> - y-intercept (0, b)</em>
We have
Substitute:
We only need two points to draw a line.
One we have: y-intercept → (0, -7).
Calculate other point:
Substitute <em>x = -3</em> to the equation of a line:
Mark the points on the coordinate plane and draw a line through the given points.
Answer:
<em>y=-6</em>
Step-by-step explanation:
<u>Proportions</u>
A direct proportion is a relation between variables where their ratio is a constant value. This means that if y and x are proportional, then:
y = kx
Where k is the constant of proportionality.
Substituting x=-3 y=9:
9 = k(-3)
Now the relationship is:
y = -3x
For x=2
y = -3(2) = -6
