Answer:
Ans:
i) y-int (0 , 2) and x-int (-2/3 , 0)
ii) y = 3x + 2
Step-by-step explanation:
<em>we know:</em>
m = 3 & point (0,2)
<em>i</em>
y-int is (0,2) because where x is 0 it intersects the y-axis
<em>ii</em>
<em>from this we can sub it into the point slope formula which is:</em>
y - y1 = m (x - x1) (y1 and x1 being the values from a point lying on the line)
y - 2 = 3 (x - 0)
y - 2 = 3x
<u>y = 3x + </u><u>2</u> < this is the equation
if you also need to find the x-int then:
to find x-int make y = 0 and solve for x
y = 3x + 2 3x = - 2
0 = 3x + 2 x = -2/3
therefore x-int is (-2/3,0)
Answer:
it would be d
Step-by-step explanation:
Step-by-step explanation:
The slope of 3 and -10.
If the slope is above 0, the line is increasing.
If the slope is at 0, it's a horizontal line or straight. Vertical If the run is 0.
If the slope is below 0, the line is decreasing.
3 is slanting upward, the slope is greater than 0 therefore the line is increasing.
-10 is slanting downward, the slope is less than 0 therefore the line is decreasing.
So, the point slope form is y-y1=m(x-x1)
To get m, you would have to use another equation, which is
4-0/-6-2
= 4/-8 = -1/2
y-4=-1/2(x+6)
I can't graph it on screen for you, but the formula is Y=mx+b where B is the y-intercept and M is the slope.
Ex- in y=2x-4, -4 is the y-intercept and the slope is 2.
