Solution : Straight line question : y= 2x-3
Straight Line:
A straight line is just a line with no curves. So, a line that extends to both sides till infinity and has no curves is called a straight line.
Slope:
The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).
Use the slope and one of the points to solve for the y-intercept (b).
One of your points can replace the x and y, and the slope you just calculated replaces the m of your equation y = mx + b. Then b is the only variable left. Use the tools you know for solving for a variable to solve for b.
Once you know the value for m and the value for b, you can plug these into the slope-intercept form of a line (y = mx + b) to get the equation for the line
1)Point (3,3) (4,5)
slope: (5-3)/(4-3) = 2/1 = 2
Y= mx+c
y -3 = 2(x-3)
y-3= 2x-6
y= 2x-6+3
y= 2x-3
