Equation 1: x + 2y = 10 equation 2: 2x + 5y = 15 step 1: −2(x + 2y) = −2(10) 2x + 5y = 15 step 2: −2x − 4y = −10 2x + 5y = 15 step 3: 1y = 5 step 4: x + 2(1) = 10 step 5: x = 8 in which step did the student first make an error? (4 points) a)step 1*i think its this one b)step 2 c)step 3 d)step 4

Find the equation of the line that goes through the points (4, –1) and (2, –5). use slope formula,equation,to find the slope of a line that passes through the points. m = use slope-intercept form, y = mx + b, to find the y-intercept (b) of the line. b = write the equation in slope-intercept form, y = mx + b.

Use the graph of the sine function y=2sinθ shown below

Which of the following equations are equivalent to -2m - 5m - 8 = 3 + (-7) + m? -15m = -4m -7m - 8 = m - 4 -3m - 8 = 4 - m m - 4 = -7m - 8 -8 - 7m = -4 + m -8 - 3m = 4 - m
