Answer:
see below
Step-by-step explanation:
A graphing calculator does this very nicely.
___
If I were graphing by hand, I might divide by 4 and add 7 to get ...
y = 3x +7
Now, you know the slope is 3 and the y-intercept is 7. Another point can be found by going left 1 and down 3 from the y-intercept, or left 2 and down 6 as shown on the attached graph. The line can be drawn through those points.
Answer:
Repersent The product of 2 and y mathamticaly
Step-by-step explanation:
Answer:
y = 7
Step-by-step explanation:
calculate the slope m using the gradient formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = (- 5, 10) and (x₂, y₂ ) = (3, y)
m = 
= 
For this to equal - 
since the denominators are equal, equate the numerators
y - 10 = - 3 ( add 10 to both sides )
y = 7
Answer:
y = 1.5x + 1
Step-by-step explanation:
→ Choose 2 points
( 2 , 4 ) ( -2 , -2 )
→ Find the gradient
-6 ÷ -4 = 1.5
→ Write into format
y = 1.5x + c
→ Substitute in ( 2 , 4 )
4 = 3 + c
→ Minus 3 from both sides
1 = c
y = 1.5x + 1
