01Find the y-value of any point on a line from its x-valuePlug a known x-value into the line’s equation in Desmos to get its y-value.
02Find the x-value that produces a given output on a lineGraph a horizontal line at the known output and find the x-value where it crosses your line.
03Explain what the x- and y-intercepts mean in a word problemThe y-intercept gives the output when the input is zero. The x-intercept gives an input where the output is zero. Use the variables’ meanings and units to interpret those values; the input need not represent time.
04Solve a linear equation with x on both sides in DesmosType the equation exactly as printed and read the x-value of the vertical line Desmos draws.
