Answer:
Slope= 7/5
Step-by-step explanation:
The slope of a line is determined as a ratio of the change in y to the change in x.
Slope=Δy/Δx
Δy=y₂-y₁
Δx=x₂-x₁
Therefore we can use the the x and y coordinates from the points given, (-3,0) and (2,7) to calculate the slope.
m= (7-0)/(2-⁻3)
Slope= 7/5
When a negative number is subtracted from a number it the operation sign changes to addition.
Multiply all terms by 2 to get rid of fractions
2x+10=28-x
Add x to both sides
3x+10=28
Subtract 10 from both sides
3x=18
Divide both sides by 3
x=6
Final answer: x=6
