How do you find the slope-intercept form given m=2,b=−3?
Solution
There are many forms to express the equation of a straight line, one of them is the slope-intercept form. The slope intercept form of a line is y=mx+b, here m is the slope of the line and b is the Y-intercept of the line. We can find the equation of the line by substituting values of the m, and b in the given equation.
Complete step by step answer:
We are asked to find the slope intercept form of the equation of a straight line for which the value of m and b are 2&−3 respectively. The slope intercept form of the equation is y=mx+b here m is the slope of the line and b is the Y-intercept of the line.
Substituting the values of the variables m, and b in the slope intercept form of the equation, we get
⇒y=2x+(−3)
Simplifying the above equation, we get
⇒y=2x−3
Hence, the slope intercept form of the equation is y=2x−3. From the equation, we can say that the line has a slope of 2, and its Y-intercept equals −3.
Note: We can express the straight line in its different forms like standard form, intercept form etc. using the slope intercept form of the equation. The standard form of the equation of a straight line is ax+by+c=0. And the intercept form of the equation of straight line is ax+by=1, for this form a, and b are X-intercept and Y-intercept respectively.
