Because this equation is in the slope-intercept<span> form</span>y=mx+b. 0=5x−13. 0+13=5x−13+13<span>. </span>13<span>=5x−0. </span>13<span>=5x.</span>
Intercepts can either be an x-intercept or a y-intercept. Both intercepts can be determined by simply setting the other variable to be zero. For instance, to obtain the x-intercept, we must equate the y value of the equation to zero and vice versa.
The decimal 0.25 represents the fraction 25/100. Decimal fractions always have a denominator based on a power of 10. We know that 5/10 is equivalent to 1/2 since 1/2 times 5/5 is 5/10. Therefore, the decimal 0.5 is equivalent to 1/2 or 2/4, etc.
